Think about this from the perspective of the user though. When I go on Facebook, I expect that whatever information I put on the site is public, regardless of privacy controls (btw, I didn't change any privacy settings when they made a fuss about it because I didn't care/ didn't understand what the difference was from before). If people don't want this information broadcasted, why post it in the first place? As an example, consider the "relationship status" feature. I don't know about you, but for most of my friends it was a running joke that you weren't "official" until you listed your status on your profile. So I think most people understand that their information is public.
