Privacy Plug-In Fakes out Facebook
Found on Technology Review on Tuesday, 08 September 2009

Now, researchers at the University of Waterloo in Ontario have developed a browser plug-in to help users keep their information private from prying eyes and from social-network providers as well.
Dubbed FaceCloak, the tool assures its users that sensitive data stays private, Hengartner says. "If you have a particular illness, you might want to allow only your friends to see that," he says. "This leaves it up to the user to decide what information to keep away from Facebook."
Or, you could just not put personal information online. I don't get that "socialize" movement; as if it's impossible to stay in touch with plain old email and IM. No, instead it looks you have to dump your whole life (which isn't really interesting at all) onto the web. And when it comes back at you, just act surprised.
