I'm on FB as well but don't play any of the games and stuff. I had already joined the "smoking meat low and slow" group a while back and mostly use FB to post pics of my cookings to tease my co-workers with.
IMO, MySpace is a wreck. I had a page on there but never did anything with it and was constantly annoyed at all the horrific layout designed my friends would come up with. Trying to read something on most peoples pages on there is enough to give you a migraine or seizure.
