I was in same state when joined facebook a few months back. Now I'm fine with using it and in a controlled way to not to get addicted to it. I'm liking a few feature of "fb" - one which I like most you don't have to keep track of things happening at your friend's end (in orkut the scraps are always one-to-one).
Yeah, I know! I lagged behind this revolution of internet but catching up.
