Facebook knows you better than your friends do.


As much as Facebook seems to annoy my peers, you’ve got to hand it to them–Facebook has collected a lot of data about a lot of us. And I’m pretty sure advertisers would like to believe that Facebook can use this information to understand us. But how well is that working out? How well does Facebook understand us and our personalities, compared to, say… our Facebook “friends”? Well, it turns out that all those “Likes” really do add up. Apparently, computer predictions based on participants’ clicks were more accurate at judging personalities than the participants’ actual Facebook friends. Not only that, but these computational predictions were also better at predicting things like substance use, political attitudes, and physical health. So go ahead and share this on Facebook… if you dare.

“Judging others’ personalities is an essential skill in successful social living, as personality is a key driver behind people’s interactions, behaviors, and emotions. Although accurate personality judgments stem from social-cognitive skills, developments in machine learning show that computer models can also make valid judgments. This study compares the accuracy of human and computer-based personality judgments, using a sample of 86,220 volunteers who completed a 100-item personality questionnaire.We show that (i) computer predictions based on a generic digital footprint (Facebook Likes) are more accurate (r = 0.56) than those made by the participants’ Facebook friends using a personality questionnaire (r = 0.49); (ii) computer models show higher interjudge agreement; and (iii) computer personality judgments have higher external validity when predicting life outcomes such as substance use, political attitudes, and physical health; for some outcomes, they even outperform the self-rated personality scores. Computers outpacing humans in personality judgment presents significant opportunities and challenges in the areas of psychological assessment, marketing, and privacy.”

How U.S. College Students Use their Technology [Infographic]


Sometimes it helps to see the numbers behinds the trends to confirm popular assumptions. In this case, Onlinecolleges.net assembled an infographic to help digest technology usage— all from student perspectives.

Most of the numbers are obvious— 87 percent say their laptop is the most important piece of tech and 78 percent say wi-fi is crucial to academic success.

But wait, it gets more interesting in items five [Most important sites] and six [Social Networking in Academic success]. Google beats Wikipedia, and Facebook beats academic-focused social networks. The crucial question is, “Why?” Could it be that Facebook was already built for college students by college students? If you have thoughts, drop us a comment or email. But for now, on to the pretty picture:

Google | Orkut departure adds another project to Google’s kitty of exits

Orkut departure adds another project to Google’s kitty of exits

Within a month of people bidding goodbye to the iconic Ambassador car, the time has come for good old Orkut to depart forever. The original social networking site that once had a huge collection of scraps and photographs is being phased out by Google due to lack of takers.

Orkut was launched early in 2004, the same year that Facebook, now the world’s No 1 social network with 1.28 billion users, was founded.

Google has announced that it will shut down Orkut, which is widely used in Brazil and India but hasn’t caughton more broadly across the rest of the world, on September 30 to focus on its other social networking initiatives.

Orkut may have lost its popularity battle against Facebook, but Google’s original social network was bigger than Facebook in emerging markets such as Brazil and India just a couple of years ago. According to comSCORE, until December 2011 Orkut was the most popular social network in Brazil.

Less than two years later, Facebook’s lead was so far ahead that it had a 74% market share compared with Orkut’s 0.97%, states a report by eMarketer.

Orkut’s growth and popularity did not last long, as Facebook emerged as a powerful social networking tool for millions. Facebook was created by a college student — the famous Mark Zuckerberg — for other college students, which emerged as a site that not only connects teenagers to friends, but other students, their families and even their favorite TV shows, movies, and stores.

Facebook also launched separate profile pages for businesses, allowing them to create events and fan pages for their current and potential consumers. Facebook transformed as a platform where programmers can create applications and games on it, that allow users to spend most of their time in the same platform without shifting to other websites.

While some may mourn over Orkut’s silent departure, Google dropping its services is not a huge surprise. Over the years the search giant has axed many of its services to create room for expanding newer projects.

In 2013-2014, Google discontinued Google Schemer (2011-2014), Google Reader (2004-2013), IGoogle (2005-2013) and Google Postini Services (2007-2013).

Last year, on July 1, many users were left unhappy and clueless when Google deactivated its Reader services. Google Reader was an RSS/Atom feed aggregator operated by Google. It was created in early 2005 by Google engineer Chris Wetherell and launched on October 7, 2005, through Google Labs. Google Reader grew in popularity to support a number of apps which used it as a platform for serving news and information to people.

Prior to this Google has also dropped Google Health (2008-2012), Google News Badges (2011-2012), Google Buzz (2010-2011) etc.

Thanks.

Pinterest review: Cleaner, easier to manage

Pinterest review: Cleaner, easier to manage

Don't worry, Pinterest fans: Your sprawling virtual pegboards of wedding dresses, handmade jewelry, craft projects and food porn haven't changed dramatically. They're just easier to manage.
The popular link- and photo-sharing website has rolled out an update, one offering people simpler navigation and new ways to arrange their boards to fit their needs. Although the haphazard spirit of Pinterest remains, the site is much less overwhelming.

I wasn't a Pinterest user before, so the redesign gave me a chance to take a good look at the site for the first time. Before that, I had refused to be sucked into yet another form of social media. I figured I didn't have much use for it.

In the months since I started testing out Pinterest's new look, though, I've found the service helpful in organizing and sharing my continually expanding recipe collection. And it's fun to check what other people around the world are looking at and to see which strangers choose to follow me or respond to what I'm sharing.

Although it is not a replacement for Facebook or Twitter, and doesn't pretend to be, it is a beautiful and vast world with more than 25 million users around the world.

For those who have never used Pinterest, the free site lets people "pin" pictures from websites they want to share on online peg boards. You can choose to share the boards with just a few close friends or the entire Pinterest world. Others can comment on the boards and pins, "like" them or repin items on their own boards.

The result is an eclectic mix of millions of boards spanning just about as many topics. Although it doesn't offer as much of a chance to communicate and debate the way Facebook and Twitter do, Pinterest is an interesting and often beautiful supplement to those social media networks.

Pinterest's recent redesign is intended to cut down on clutter and make the site easier to manage, without drastically changing its look. The new look continues to evolve. Most of the changes are very subtle, and some have been tweaked or reversed already, helping Pinterest avoid the kind of backlash that Facebook has weathered in the past. Pinterest promises even more updates in the weeks and months ahead.

One of the most noticeable changes so far is Pinterest's move to larger pins, so you get four rather than five items per row. The site looks cleaner and less overwhelming because you don't see as many items on the screen at once. Much of the text previously found on Pinterest boards is smaller or gone. Menus have been streamlined.

What impresses me most about Pinterest - and also what drove me crazy - is its vast variety. Although there's no shortage of boards devoted to food, clothing, gadgets and home decor, there are also ones devoted to obscure topics such as doors, hockey goalies and the character Daryl from the TV show "The Walking Dead."

Some boards are very artistic and personal, while others, like mine, are more practical than pretty. The possibilities are endless, and so is the potential for wasting time - another reason I held off on joining for so long. Basically, whatever you're obsessed with, there's something on Pinterest for you.

For me, that's food.

I have hundreds of food-related sites bookmarked on my work and home computers, plus my iPhone and my iPad. They cover healthy recipes geared toward using up ingredients from my weekly farm share, tips for cooking a filet mignon and lists of New York restaurants with the best ramen and pizza. Other people have shared everything from the most ornate wedding cakes to those old-fashioned casseroles held together with canned soup.

Pinterest became a handy way to organize all that. First, I set up a Pinterest board simply titled "Recipes." That quickly spawned separate boards for easy meals, desserts and New York City restaurants. Although they pale in size so far to many of the countless other recipe boards out there, I find myself adding a couple things every day as I browse Twitter, Facebook and, of course, other Pinterest boards.

The boards also serve as a handy way for me to share recipes. Want my go-to red velvet cake, mac and cheese and turkey chili recipes? They're all on my Pinterest page. It also gives me easy access to my recipes when I need them. Rather than emailing myself links to recipes that I've bookmarked on my office computer, I can just pin them to my board and open up it later on my iPhone as I walk through the grocery store or on my iPad as I stir something on the stove.

After just a few months, some of my boards have grown pretty large. The new, less cluttered version of Pinterest helps me find what a need a little faster.

The activity feed, which details who likes and repins your pins along with other information, is in the process of moving to a drop-down menu on the right-hand side, clearing more space for the pins and their often beautiful photos. Its content is expanding as well. Notifications go back further in time than what users previously saw.

Filtering boards and pins by topic, such as "Art," "Food & Drink" and "Geek," is now easier, too. Instead of one long list dropping down from the middle of your page, the categories fall from the upper left in three shorter columns. It's a simple change that makes the list less daunting to read through. Meanwhile, all of the profile and account settings have been consolidated in a dropdown menu on the right.

A plethora of new information also pops up now when you take a close-up look at a pin. To the right of the pin is a mini version of the board it came from, which you can scroll through. There is a mini board showing other pins from the same website, so you can discover related recipes, for instance. Below all of that is a collection of pins from people who pinned the pin you're looking at. It's a way to discover material from like-minded people. It's a lot of content on one page, but surprisingly manageable.

Pinterest has also boosted its search capabilities, so that when you start typing something in the search box located in the upper-left corner of the page, a list of suggested words appears below it. That's helpful if you don't know exactly how to spell something.

But some popular features have also been eliminated. Gone is the site's "originally pinned by" feature, which showed which user was the first to pin a certain item. But Pinterest notes that many users have requested its return. I wouldn't be surprised if it did. Based on user feedback, Pinterest has already brought back other features, including one that allows users who have just pinned something to look at related pins or go straight to their pin by clicking on its "see it now" button.

What makes Pinterest different from other social media services is that it's not so much about posting your opinions or even letting your friends know about what's going on in your life. Instead of creating new content, it's about sharing and organizing what's already out there, preferably content that's attached to cool photos.

You get a beautiful visual experience and links to just about everything online right now.
