One month with Google+: why this social network has legs




If you're a stranger who follows me on Google+, you might think I rarely use the service. That's because the majority of my posts have been limited to the seven circles I created for friends, acquaintances, family, Ars staffers, and other people I like to expose to various aspects of my personality. You had no idea? That's exactly the point.
After one month with Google+, it's clear to me that this—sending updates to certain groups of people and not to others—is the main appeal of the service. I was one of the first people to loudly declare that you can do the same thing on Facebook, but so few people know this that it's basically a nonexistent feature; that's the problem with Facebook. With Google+, sending out certain updates to some people and other updates to other people is right at the forefront of the experience. You are always asked to make a conscious decision about your social circles and about which circles get to see which posts.
Some people don't like this approach. I do, but it took a while. Truth be told, I was a fierce skeptic of Google+ when it was first announced, and I wasn't pleased at the idea of using it every day for a month. (Every singleday?) As the Ars forums might say, Google+ was Yet Another Social Network (YASN), and one led by the company behind the spectacular privacy failure that was Google Buzz. Google's previous social network, Orkut, failed to impress (at least, in the US), and the prospect of dedicating my time to YASN wherein I would interact with the same people I already know through Facebook or Twitter was not appealing.
But Google+ has grown on me. Despite some of its latest struggles, I think Google has a leg to stand on with its latest social venture.

What Google+ has going for it

Because most of us like to frame the unfamiliar with the familiar, let's get the necessary comparison out of the way first: Google+ occupies a space somewhere between Facebook and Twitter, but I think it falls closer to the former. Features match Facebook in many ways, but it's the implementation and presentation that makes them starkly different.
Let's start with posts and Circles—the core functionality of Google+. Posts themselves translate to Facebook wall posts or to tweets, while Google's "+1" button translates to Facebook's "Like" button.
Google+'s Circles translate to Facebook's lists but not to Groups (I'll go more into that later). Google+ prompts users to categorize every single person in their life into some sort of Circle, and those people won't be able to see any of your non-public posts unless you do so.
On Facebook, lists are virtually unknown (and are in the process of being supplanted by Facebook Groups) and Facebook users are subconsciously pushed toward public disclosure thanks to default settings and the general UI. Google+ takes the opposite approach; the predominant thought when you go to make a Google+ post is, "Who exactly will see this?"
Because Google+ pushes the Circles so hard, divvying up your posts among different groups of people is at the forefront of the experience. Those who find this laborious tend to be heavy Facebook users, which is understandable—they're not used to facing this decision every time they make a post, and it's undoubtedly annoying to them. But for those of us who have always been trying to find ways to share information with friends while limiting exposure to others, Circles can be a blessing. Simply forcing users to always think about the distribution of their posts is in itself good for privacy.
The area where you choose which circles get to see your post is prominent and colorful; it's right out in front, unlike Facebook.
Compare this to Twitter. Some people like to maintain two (or more) Twitter accounts in order to separate out different aspects of their lives. This has been going on since the beginning of Twitter, but seems to have increased in recent years over increased awareness about privacy. Someone might have a private account for close personal friends but still maintain a public account for everyone else; someone else might have an account for just his own musings while maintaining a second for links he wants to share. 
This is an imperfect solution, and it quickly becomes cumbersome to manage more than one Twitter account. (While using Circles may be a tiny bit tedious, it's no comparison to this kind of account switching.) Google+, on the other hand, allows you to maintain a single, unified account where you don't have to switch between log-ins. I can share a link to a story I wrote with one Circle while talking about some of my life concerns with another, more intimate circle, and the two don't have to cross if I don't want them to.
Even better is Google's tool that lets you see your own profile page from another user's perspective. Want to make sure your mother can't see a post you made about puking at the bar? Type in her name (assuming she has a Google profile—if she doesn't, then she's just public) and see which of your posts show up for her. Or say you have a post about sex toys (gasp!) and you don't want the big boss to see. You may know in your heart of hearts that you marked that post friends-only, but if you want to confirm it, you can. I plugged in mybig boss to show you what this looks like:
The red bar shows who I am seeing my profile as, so that I can verify which posts that person can or can't see.
The tool is simple but effective, and it can certainly help to head off embarrassing over-sharing. In fact, while taking the above screenshot, I discovered that I had accidentally added a (very) loose acquaintance to my "Close Friends" group instead of to the "Acquaintance" group, allowing him to see some of my more private observations. That was a very helpful discovery.
There are other benefits, too. There's no character limit to Google+ posts, meaning that you have much more freedom than the 140 characters allowed by Twitter and—I didn't even know this before writing this article—the 400 character limit imposed by Facebook. This provides the freedom to treat Google+ like a blog, but most people don't (yet) do so, and it's not particularly annoying at this point. I have already used Google+ over Twitter several times for the express purpose of asking longer questions of the general public.
Don't want to hear about this post anymore? No problem: just mute it.

Content controls

There's also the (wondrous) ability to "mute" posts on Google+. You know how you "Like" a friend's photo on Facebook, only to get alerts for every single one of that person's 300 family members when they end up commenting on the picture and arguing over whose body part is in the corner? Imagine if you could simply hit a button to ensure that you never have to hear about that post ever again—even if it's your own post. We're not talking about blocking certain users—sometimes you want to keep a person around, but you just don't want to hear about a topic anymore. That's a huge bonus to Google+, and those I've spoken to agree that it's one of the better unsung features of the service.
Access this menu by clicking the little dot/gear next to your post.
Google+ also offers the ability to re-share posts made by others. Twitter's retweet feature is similar, where the other person's content shows up in your own feed as something that you have "forwarded" onto your own followers. This in itself is handy, but Google+ takes it a step further by also offering options not to allow re-sharing (say you make a private post to a small group of people and you don't want those people re-sharing your thoughts to their own friends). The same goes for comments—comments on every post are on by default, but you can turn them off for any specific post if you simply don't want to hear from the peanut gallery this time around.
Google presents its options in a way that acknowledges organization (and thus, privacy) first, whereas Facebook acknowledges organization and privacy as an afterthought, while organization barely exists for Twitter and privacy is an all-or-nothing venture. Google+ also has other neat features, such as the video-based Hangouts that let multiple users get together online and watch things like YouTube videos in an Internet group setting. Though I don't consider Hangouts to be a core reason to use Google+, plenty of users seem to like it, so good for them.

What the competition has going for it

Google+ is not the end-all, be-all of social networks—and Twitter or Facebook have their own strengths.
Facebook Groups are good for actual groups of people, all of which have equal input into a shared "room."
To take one example, although Facebook lists have some of the same functionality as Google+ Circles, Facebook also has Groups, which sort of have the same end goal but operate much differently. Facebook Groups essentially act like a private "room" in which a group of people can share things. For example, if you're familiar with Facebook events, it's like having an event page where everyone who was invited can leave comments and share items, but without the party attached. Everyone is on equal ground when they are invited to be part of a Facebook Group; it functions like your own private group wall.
This is especially handy for actual groups (as in, not just your clique), such as book clubs or running groups—people who want a centralized place for just themselves to share information, links, commentary, etc., and for everyone to have the opportunity to share equally.
Compare that to Circles (or to Facebook lists), where you create the list of people and then you make posts that go out to those specific people. People in your Google+ Circle cannot make posts that go out to the other members of your Circle unless they create their own Circle that mirrors yours. And if they create their own Circles, there may be other members in those Circles who aren't necessarily included in your Circle on the same topic. This is an obvious downside to Circles and an upside to Facebook Groups for sharing among members of a group.
Most importantly, what both Facebook and Twitter have is what every social network needs to succeed: a wide and active audience. Google+ is seeing a respectable amount of success—certainly much more success than any other new social network has seen in years—but there are plenty of reasons why the masses will remain at their old haunts for a while. Many people stick to Facebook because that's where their real-life friends and family members are, and that's a perfectly valid reason to stay. The same goes for Twitter: people use it to blast observations and information to their followers in a quick-moving and bite-sized manner, and that's exactly why it has been so successful.
Neither of these services will be displaced in the immediate future by Google+, and most Google+ users still use one or both of the others as their "main" social network. That goes for me, too.

But Google+ will stick around

During my month of using Google+ every day, I've already seen signs that the initial rush to check the service out has ended—there's less activity now than there was, say, during its first two weeks. But what's also clear is that a core base seems to be sticking around, and I believe they'll remain long enough to see Google+ establish itself as one of the main networks that Real People™ actually use.
Yes, Google+ has already run into a number of issues in its first month—there was a weekend recently in which a plethora of accounts were swiftly and mysteriously deleted, and it was only revealed later that Google was attempting to enforce a "real name" rule that many people didn't know about. There were also some transparency and consistency issues that turned the whole episode into a minor debacle.
Google+ could also use improvement. For example, the notifications menu on the Web app is borderline useless, communicating as little information as possible while constantly bugging you at the top of nearly every Google-related Web app in existence. (Really? Google can't even give me a hint about which post my friend commented on before I click? There's an awful lot of space where that information could live.) Then, when you click on any item in the list, the entire list marks itself as read! Could this menu and its functionality be any more frustrating?
But such problems are growing pains. Google seems to be taking this project more seriously than some of its other recent efforts, and the company has said multiple times—to the media and on Google+ itself—that it is listening closely to user feedback. Additionally, the company has said that it has plans to expand Google+ support throughout its other services; this is just the beginning.
However, the most important thing for Google to do right now is to retain its current audience and keep the momentum going. Enough people use Google+ and say enough good new things about it that it could establish itself as a legitimate alternative to Facebook, but fickle users can easily be driven away by boredom at this early stage. So long as Google+ keeps improving, it should be okay; if it implements some of the suggestions thrown out by its users, it could be more than okay.
As for me, I have always used Twitter (lots) more than Facebook, and I have always been a little allergic to other services. I still use Twitter the most, but now I use Google+ on a regular basis and Facebook barely at all. Even the thought of going to Facebook seems a little old-fashioned to me when I could be using Google+.
Google+ has legs. Now it's up to Google to see how far it can run.

Facebook Blocks The Secret iPad App

Well, it was fun while it lasted.

Just last night, our own MG Siegler unveiled that Facebook’s top secret iPad app was hiding in plain sight right within the publicly available iPhone app. All it took was a quick, mostly-pain-free modification or two, and you were knee deep in unexplored Beta territory.

Alas, it looks like Facebook has found a way to close things back up.

We’re hearing tons (as in hundreds) of reports that users who are just now getting around to checking out the trick are unable to do so. The iPad-friendly app still launches — you just can’t do much, as newcomers are being turned away at the login screen.

Oddly, it seems that those who managed to sneak in to the party before Facebook started closing the gates are still on the guest list.. to some extent. MG is still able to click around the app, though certain things (like notifications) are acting strangely or not functioning at all. No word yet on whether they plan to give everyone outside of Facebook HQ the boot completely.

Oh well. If all else fails, you can always load all the photos from our full photo gallery into your iPad’s photo app and pretend.

Who is Anders Behring Breivik? Norway shooting suspect's profile emerges



The killer behind Friday's bloodletting in Norway is a boyishly handsome, blond-haired anti-Islamic nationalist interested in politics, violent video games and the T.V. show "Dexter."
Anders Behring Breivik, a 32-year-old Norwegian national, claims to be a fan of Winston Churchill, classical music, and gory movies like, "300," and "Gladiator," on his Facebook page.
He also claims on the page to be a fan of the sappy HBO vampire drama, "True Blood," and the serial killer show, "Dexter."
Breivik, who was reportedly a Free Mason at one time, has been fingered for the dual attacks that claimed more than 7 lives in the capitol of Oslo, and 80 campers on the island youth retreat of Utoya.
Authorities are still trying to decipher the motive for Friday's coordinated killings, but a rough portrait of Breivik as a politically-engaged man with strong views has emerged.
The youth camp on the island of Utoya is reportedly owned by the Norwegian Labor Party, while the Oslo bomb blast was outside a government office.

The shooter belongs to "right-wing circles" in Oslo, the city in which he resides, according to Norwegian TV2. Meanwhile, The Huffington Post cites the Swedish news site Expressen as saying that he is a "self-described nationalist who has also written a number of posts critical of Islam."
He studied at the Oslo Commerce School, an instituion devoted to business and financial management.
In published photos, the alleged killer is shown to don a half smile, preppy clothing, and piercing green eyes that stare into the camera.
The Huffington Post goes on to cite a Twitter account for Breivik, in which he chillingly quotes the philosopher John Stuart Mill, saying, "One person with a belief is equal to the force of 100,000 who have only interests." The tweet was posted on July 17 and was the only one attributed to the account.
Breivik may have used a front company, Breivik Geofarm, he founded in 2009 as an excuse to legally stockpile large quantities of fertilizer and other chemicals which he could have used to build the bombs, according to Norwegian news stations.
On his Facebook page, Breivik describes himself as a fan of shoot-em'-up video games like "Modern Warefare 2," as well as the fantasy epic, "World of Warcraft."

Facebook vs Google+: Who beats Whom?


It is three weeks old and still not out of the labs but Google+ already boasts over 10 million users. What's drawing in the new fans?

Unabashed imitation of Facebook's key inventions and a clutch of great innovations of its own.

Here's a feature by feature comparison of the newest social networking rivals.

Posts vs Wall

/photo.cms?msid=9253368
/photo.cms?msid=9253369



A blatant copy: G+ posts are styled like FB's except one addition: you can disable reposts (they're like retweets) and comments right there.

Stream vs News Feed

/photo.cms?msid=9253402
/photo.cms?msid=9253403


Remove the signature Facebook Blue and you can't tell Stream from Feed. Imitation is the best form of flattery. Or maybe an admission Google couldn't think better?

Circles vs Lists
/photo.cms?msid=9253420
/photo.cms?msid=9253422


A winner for G+. 'Circles' are groups to categorise people you know and share posts, feeds or photos exclusively. Basic Circles like 'Friends' and 'Family' are preloaded but you can create your own. (Think 'work monsters'). Compared with this, FB's Lists is plain boring.

Hangout vs Video call

/photo.cms?msid=9253457
/photo.cms?msid=9253461


The cracker. Hangout allows up to 10 people to video chat together. Tiny feeds of buddies line up the bottom of your screen with a big image of the person talking. There's a window for text chats and a button for watching YouTube . FB's latest one-on-one video chat just doesn't make the cut.

+1 vs Like

/photo.cms?msid=9253482
/photo.cms?msid=9253484


There is something about saying I 'Like' that just isn't in I '+1'. But Google is using it to make its search social too.

Rihanna Is The New Queen Of Facebook, Beating Out Lady Gaga

Numbers, stats, and figures were also the subject of another news story this week involving a popular female entertainer. Matthew Knowles, father and former manager of Beyoncé, filled legal papers in Texas, alleging his daughter's new management team accused him of stealing money from her, claims he vehemently denies. And in even more shocking family news, power couple Jennifer Lopez and Marc Anthony announced their plans to divorce, a month after their seventh anniversary.

 Lady Gaga may be the top earning woman in music, have more followers on Twitter than any other lady rock star and receive more media coverage than her female competitors, but she is no longer the queen of Facebook.
This week, Rihanna accumulated enough likes on Facebook to surpass Lady Gaga and claim the throne as the platform's top ranking female celebrity.
According to their Facebook stats, as of Saturday, Rihanna had 40,699,853 likes, and Lady Gaga had 40,611,908, giving the "Rude Boy" singer a lead of 88,000.
Shakira is the diva with the third most Facebook followers, according to Famecount.com, which credits the Latina singer with 37 million likes. Aside from being the top three female musicians on Facebook, they also have earned spots in Facebook's top 10 pages overall. Rihanna, Lady Gaga, and Shakira hold the No. 5, 6, and 8, positions, respectively.
There are three men on the Top Facebook Pages Worldwide list as well. Eminem ranks No. 3 with 43,367,713 likes. The late Michael Jackson sits at No. 7 with 38,069,882 likes, and "Baby" singer Justin Bieber holds the No. 10 position with 33,035,903 likes.
Pop star Jewel and her husband, Ty Murray, fortunately, have a happier home front. This week, they announced the birth of their son, Kase Townes. And legendary music shero Cher sang Lady Gaga's praises this week after recording for her new album "The Greatest Thing," a song written and produced for her by Gaga and RedOne.
For more details on these music stories, see the links below, and be sure to check back with us next week for another music news roundup. See you then.

How Facebook saved a child's life (and could save many more)



Facebook saves lives. Or more to the point, good Facebook friends save lives.

Slate writer and novelist Deborah Copaken Kogan credits her community on the social networking site for helping diagnose her son’s mystery illness in time. Kogan woke up on Mother’s Day to find her 4-year-old son Leo with a rash and a fever.

In the pediatrician’s office, she updated her Facebook status with a photo of her son’s reddened face and the comment: “Nothing says Happy Mother's Day quite like a Sunday morning at the pediatrician's." As his symptoms worsened—high fever, swollen face—she continued sharing photos and concerns to a growing community of friends and ‘friends’.

"Baby getting sicker. Eyes swollen shut. Fever rising. Penicillin not working. Might be scarlet fever. Or roseola. Or...???? Sigh,” she wrote. Ten minutes later she got a call from a friend who saw the update and offered some sage advice: get to the hospital. Kogan’s friend had seen these symptoms before when her own son had Kawasaki disease, a rare and potentially fatal illness that accelerates in days and may lead to a dangerous heart condition.

Two other Facebook friends, both pediatricians, also saw her status update and sent the same diagnostic warning. “As much as I wanted to be my usual mellow self, the immediacy of the Facebook feedback was enough to push me out the door,” writes Kogan on Slate.com.

It wasn’t long before their feedback was confirmed: Leo had Kawasaki disease. Two months later, he is still recovering from the disease that wreaked havoc on his heart and liver. But the outcome could have been much worse and Kogan is grateful for the instant ‘in-network’ advice and support.

Her story is unique but not the first of its kind.  Last year, a pediatric nurse spotted cancer on her friend's child after scrolling through her Facebook photos, effectively saving her life. And when a 56-year-old woman slipped into a coma, doctors turned to her detailed Facebook status updates on her health for an outline of her symptoms and medical history.

All three are stark examples of how this new-found and sometimes odd lack of privacy can be a saving grace. Could our culture of over-sharing actually be leading us down a road to improved healthcare? Is friending a doctor on Facebook a shortcut to a faster diagnosis?

Not if the British Medical Association has anything to say about it. They recently released new guidelines for members, urging them not to blur the lines between work and play by accepting Facebook requests from patients. Lack of privacy and liability fears are just part of the trade-off for instant, free health advice between ‘friends’.

But the model of instant patient-to-provider and patient-to-patient advice is in place thanks to the Mark Zuckerberg model. Now the Mayo Clinic is jumping on the trend with a new Facebook-esque social networking site for their own hospital patients and providers to communicate freely. “We want to provide the latest technology and enable the community to evolve in the directions it wants to go,” says the clinic’s social media director Lee Aase. Their goal is to let “the community define what is useful.”

For now, it seems, what’s most useful is having friends who care, even if you've only met on Facebook.

Now, hide Facebook from your boss by converting it into an Excel sheet!

 Now, you can easily check your Facebook account at your work place without the fear of being caught by your boss.

A website developed by a university student allows you to automatically convert your Facebook news feeds into an Excel spreadsheet, reports the Herald Sun.
Users can instantly see what their friends are up to on Facebook with updates appearing as new spreadsheet rows.

Uploaded pictures and videos can be viewed by hovering over the entries, and users can interact by "liking" the updates with a simple click on the spreadsheet.

The page, with its intentionally corporate look, is slyly titled "daily cash reconciliation" so wasting work time appears to nosy onlookers as diligent financial work.

The HardlyWork.in site was created by Yale computer science major Bay Gross, 20, after a friend doing a government internship told him she had to wait until after work to read his Facebook updates.

Facebook trapped in MySQL ‘fate worse than death’

According to database pioneer Michael Stonebraker, Facebook is operating a huge, complex MySQL implementation equivalent to “a fate worse than death,” and the only way out is “bite the bullet and rewrite everything.”
Not that it’s necessarily Facebook’s fault, though. Stonebraker says the social network’s predicament is all too common among web startups that start small and grow to epic proportions.
During an interview this week, Stonebraker explained to me that Facebook has split its MySQL database into 4,000 shards in order to handle the site’s massive data volume, and is running 9,000 instances of memcached in order to keep up with the number of transactions the database must serve. I’m checking with Facebook to verify the accuracy of those numbers, but Facebook’s history with MySQL is no mystery.
The oft-quoted statistic from 2008 is that the site had 1,800 servers dedicated to MySQL and 805 servers dedicated to memcached, although multiple MySQL shards and memcached instances can run on a single server. Facebook even maintains a MySQL at Facebook page dedicated to updating readers on the progress of its extensive work to make the database scale along with the site.
The widely accepted problem with MySQL is that it wasn’t built for webscale applications or those that must handle excessive transaction volumes. Stonebraker said the problem with MySQL and other SQL databases is that they consume too many resources for overhead tasks (e.g., maintaining ACID compliance and handling multithreading) and relatively few on actually finding and serving data. This might be fine for a small application with a small data set, but it quickly becomes too much to handle as data and transaction volumes grow.
This is a problem for a company like Facebook because it has so much user data, and because every user clicking “Like,” updating his status, joining a new group or otherwise interacting with the site constitutes a transaction its MySQL database has to process. Every second a user has to wait while a Facebook service calls the database is time that user might spend wondering if it’s worth the wait.

Not just a Facebook problem

In Stonebraker’s opinion, “old SQL (as he calls it) is good for nothing” and needs to be “sent to the home for retired software.” After all, he explained, SQL was created decades ago before the web, mobile devices and sensors forever changed how and how often databases are accessed.
But products such as MySQL are also open-source and free, and SQL skills aren’t hard to come by. This means, Stonebraker says, that when web startups decide they need to build a product in a hurry, MySQL is natural choice. But then they hit that hockey-stick-like growth rate like Facebook did, and they don’t really have the time to re-engineer the service from the database up. Instead, he said, they end up applying Band-Aid fixes that solve problems as they occur, but that never really fix the underlying problem of an inadequate data-management strategy.



There have been various attempts to overcome SQL’s performance and scalability problems, including the buzzworthy NoSQL movement that burst onto the scene a couple of years ago. However, it was quickly discovered that while NoSQL might be faster and scale better, it did so at the expense of ACID consistency. As I explained in a post earlier this year about Citrusleaf, a NoSQL provider claiming to maintain ACID properties:
ACID is an acronym for “Atomicity, Consistency, Isolation, Durability” — a relatively complicated way of saying transactions are performed reliably and accurately, which can be very important in situations like e-commerce, where every transaction relies on the accuracy of the data set.
Stonebraker thinks sacrificing ACID is a “terrible idea,” and, he noted, NoSQL databases end up only being marginally faster because they require writing certain consistency and other functions into the application’s business logic.
Stonebraker added, though, that NoSQL is a fine option for storing and serving unstructured or semi-structured data such as documents, which aren’t really suitable for relational databases. Facebook, for example, created Cassandra for certain tasks and also uses the Hadoop-based HBase heavily, but it’s still a MySQL shop for much of its core needs.

Is ‘NewSQL’ the cure?

But Stonebraker — an entrepreneur as much as a computer scientist — has an answer for the shortcoming of both “old SQL” and NoSQL. It’s called NewSQL (a term coined by 451 Group analyst Matthew Aslett) or scalable SQL, as I’ve referred to it in the past. Pushed by companies such as Xeround, Clustrix, NimbusDB, GenieDB and Stonebraker’s own VoltDB, NewSQL products maintain ACID properties while eliminating most of the other functions that slow legacy SQL performance. VoltDB, an online-transaction processing (OLTP) database, utilizes a number of methods to improve speed, including by running entirely in-memory instead of on disk.
It would be easy to accuse Stonebraker of tooting his own horn, but NewSQL vendors have been garnering lots of attention, investment and customers over the past year. There’s no guarantee they’re the solution for Facebook’s MySQL woes — the complexity of Facebook’s architecture and the company’s penchant for open source being among the reasons — but perhaps NewSQL will help the next generation of web startups avoid falling into the pitfalls of their predecessors. Until, that is, it, too, becomes a relic of the Web 3.0 era.
