I think what's really interesting is that people are just accepting friend requests left and right. What's the point of 'friending' people you don't even know? Is it to boost your friend count as though that holds some sort of social credibility? Are people really that insecure/lacking that much self-esteem that they want to 'friend' everyone?
Back when I used Facebook, I only ever accepted people whom I was actually friends with and spoke to on a regular occurence. Sure, I only had a few dozen friends on there, but I'd go for quality over quantity anytime.
