My roommate's boyfriend actually attempted to send out friend requests to everyone at our university, and nearly every one of them was accepted. It's really amazing how many people you've never even seen before will accept you as a "Facebook friend." Of course, we at Duke apparently Facebook whores, so maybe it's just us.
Personally, I'm extremely lazy and never friend anyone, mostly because I can't remember people's names long enough to try to find them, and the pictures don't help.
