Many privacy evangalists, like Dan Yoder, have taken facebook to a beating , as far as recommending you quit. This follows a series of Privacy policy changes from Facebook on an excuse to protecting themselves. It turns out Dan's points have quite a few compelling reasons to actually quit. However, personally, I would not - but would definitely advice a lot of caution to use ANY of FaceBook's features. Always protects yours and your friends' information. Reduce the visibility of any information to minimum or atleast only to your friends. And if possible omit it all together. As a general rule of thumb – only let that information go into facebook that has NO implication whatsoever, if revealed. To ANYONE – And I mean - your boss, collegues, girlfriends, wifes (ex-wifes :P). For quick reality check how much can be dug out of your facebook profile WITHOUT logging in, you can head on to http://zesty.ca/facebook/ . And remember, this is as much information ANYONE can get.
