(Coming a bit late to the party but) As Bob said... When Facebook is involved, there is no privacy. Period. The end. Do not pass go, do not collect $200. The entire business model of Facebook is built around selling people's information, private or otherwise. Do not post anything there that you wouldn't want potentially shared with the entire world. Also make sure to look into how much information you're giving up every time you "like" something.
