It seems as if the ol' super official privacy notice is making its rounds on Facebook again. For your edification, in case you were planning on posting it yourself, it does nothing. It may seem like it's legit because it's written in semi-legalese, but it's basically a glorified "keep off the grass" sign.
Look, we already went through this crap with the Facebook Gold Account craze, or when people thought Facebook was about to charge them a monthly rate unless they posted something into their status. You might use Facebook as your personal social playground, but you don't have any control over your information; Facebook does. Anything you say or do on Facebook has absolutely no bearing on your account, your life, or the real world but to bounce around your friends' news feeds and stuff another nickel into Mark Zuckerberg's brimming coffers. The sooner you get over that, the better.
