I have a Facebook account. I currently have about 7 "friends" (that should just be renamed "connections to you" kind of thing) and of those 7, I really only know 4; and out of those 4, only 2 of them I communicate to them often. I opened my Facebook account back last March, and it wasn't a pretty beginning, not worth going into. I added a few more friends last fall, but I don't talk to the often, nor do they initiate a conversation to me ether.
Facebook as a whole is a great site over MySpace in a technical standpoint, but when it goes to the users content, I don't really care, never mind Facebook is a site for liberals (sorry for my political rant) and lots of profiles of wild people.
I am tempted to create friends towards people whom I don't know, but I fall back because I don't know how they are going to react on the other end. My first run-in with someone that I sorta knew went sour because I didn't know how to communicate via the Internet with people that I don't even know.
I never gotten many friends on ether my MySpace or Facebook accounts, never got many hits (only north of 400 on my MySpace), messages to people didn't get returned and if I got any friend requests, they were spam.
I guess, I should network the old fashioned way.
