I'm on facebook and I love it for keeping in touch with friends from far away. I've moved so much that it became increasingly hard to stay in touch. Facebook puts it all into one place for me. I've also discovered some connections that I didn't know existed (like my best friend from when I was 8 is good friends with my college boyfriend and his wife!).

I only befriend people whom I actually want to know. I share my profile with all of them, but there is nothing in there that you can't find out by googling my maiden name (it's extremely unique). I'm only facebook 'friends' with internet friends whom I actually know something about it real life.

It's made it a great resource for me for meeting up with old & new friends. And when someone from my HS wants to 'friend' me but yet chose to ignore me back then...they get ignored by me now. I see no point to befriending people based solely on the fact that we were in the same class at school. If I didn't like them then, I'm not going to let the internet change my connection to them now. In my mind, the definition of the word 'friend' doesn't change just because internet based networking sites exist.
