Now I'm not one to worry overly much about online privacy. Partly this is due to me not ever really telling the internet anything much about myself, but mostly it's because I'm reasonably certain that no one could maintain interest in my personal details long enough to make any use out of them.
Anyway. We all know Facebook's a bit hit-and-miss when it comes to looking after our personal data, right? But I found this thing online, and it scans your settings and tells you if, like, bogey men can find out stuff about you from Facebook. You should try it.
