Facebook announced this week that they were beta-testing a new feature on the massively popular social network, called "Questions." The concept is quite simple, and one that many of us are intimately familiar with. Facebook users can pose questions, which will show up not only in their friends' feeds but in a public question directory, and can similarly provide answers to other users questions.

This week should be a celebratory milestone for Facebook - the world's largest social network just keeps getting larger and larger, although founder Mark Zuckerberg has admitted that growth has slowed in recent months. Instead of a celebratory atmosphere, though, Facebook is caught up in the midst of what may turn out to be the ugliest ownership fracas in the company's history - andthat's saying a lot, considering that Facebook has given lucrative ownership stakes to multiple individuals who claim that Zuckerberg copied key concepts and even code to create Facebook.

Coca-Cola became the latest company to completely screw up a social marketing attempt this week, joining the ranks of brands like Molson, Nestle and rival soft drink Pepsi, all of whom have tried in the past to leverage the awesome power of social media and viral marketing, only to see their experiments blow up in their faces. Coca-Cola's faux pas this week is a particularly embarrassing failure, since it might very well result in legal action being taken against the company, which is accused of exposing minors to pornographic material following a Dr.

Oh, snap! Facebook founder Mark Zuckerberg got a nasty surprise this weekend when, in the middle of a swanky lunch in Sun Valley, Idaho, he got served. Although I unfortunately wasn't there to see it myself, I'm assured by reliable sources that it looked something like this:

The big news spreading around Facebook last weekend was that the world's largest social network was going to be begin automatically tagging your friends' faces in your photographs, spurred on by articles with headlines that misrepresent Facebook's new face-detection features, like this one on CNN (Facebook to Recognize Faces, Help Tag Photos).

The first trailer for the upcoming movie about Facebook, "The Social Network," has been released, and it's an interesting watch. Ultra-minimalist, the trailer doesn't actually show any of the actors in the movie, simply using text and audio clips from the movie to convey a sense of seriousness.

The latest hot rumour in the world of social networking is that Google is developing what some industry insiders are calling a "Facebook killer" - a new Google-run social network, patterned after Facebook, codenamed "Google Me."

With all of the Facebook privacy changes that have come around in recent months, you'd think that people would be more aware of whether or not their Facebook profiles are set to be publicly visible by default. Facebook profiles that are publicly visible can be viewed by anyone - even people who aren't on Facebook. Many users who followed Facebook's "recommendations" for privacy settings may have inadvertantly set their Facebook profiles to be publicly visible - a huge mistake.

According to a fascinating interview with Facebook founder Mark Zuckerberg this week on Inside Facebook (Discussing the Future of Facebook and the Facebook Ecosystem with CEO Mark Zuckerberg), Facebook admits that they may have focused too much on trying to emulate Twitter, the fast-growing microblogging platform, when formulating their strategies and plans for the future.
