I've found myself wondering; with the information that people give out on such places as MySpace.com and FaceBook.com what you could do to someone who you walk past almost every day between classes. For instance from Facebook alone they can enter their classroom information, you can see who their friends are, their interests, websites they might have, etc (including where they live and phone numbers). There is enough information there to thoughly pretend like you know someone. I almost think it should be done to some people so they realize just who has access to their information. I however am not gutsy enough to do that. (As entertaining and educational as it would be.)
Just something for thought, be careful what you put on the net.
