Privacy on Facebook is essentially a myth at this point. They keep adding and changing settings to make users feel like they have control over who can see what they're posing, but in reality anything you put on Facebook, regardless of settings, has the potential to wind up in the public eye. It can even happen if you're related to the creator of Facebook . Randi Zuckerberg, Mark Zuckerberg's sister, had a photo she posted privately go public on the Internet. If a member of the Zuckerberg family can't even get some privacy on Facebook, what hope is there for the rest of us?
Facebook's one of those companies that's notorious for attempting to purchase any other company that they determine to be within their wheelhouse. It's pretty much the driving reason behind their acquisition of Instagram. If you can't beat 'em, buy 'em. That's why when Snapchat, an app that sends self-destructing pictures, hit the market, it's not surprising to learn that Facebook tried to acquire them. When that didn't pan out, Facebook built their own Poke app, which is basically the same thing. What's actually interesting about the app is that Mark Zuckerberg himself supposedly worked on it, and even used his own voice for the notification sound.
