I joined it to play Scrabble (which I do with about two people) but I don't really see the point apart from that. I too get stuff (usually unseasonable or pig- and hen-related) thrown at me, plus annoying chain mail which stops right here. I know people use it as a networking site to see what their friends are up to, but it seems to me you can't have a decent conversation the way you can here.

I also don't get Twitter.

Eep. Am I turning into an old fogey? Nope, I'm just an introvert. I like being in control of when I respond, and enjoy LJ and e-mail, but not the phone, texting, and IM. It's a personality thing, and I know others enjoy the immediacy of those things.
