As the creators of Openbook explain, Facebook "do not go a good job of indicating how public each piece of information you share on the site will be. Second, they change the rules far too often. If you understood Facebook's privacy settings two years ago (or even six months ago) that information would be worse than useless with today's bewildering settings."

Take a look at the information people share - whether they like it or not.
