I wouldn't be surprised if he didn't already know that.
Expect a harsh reply.
Anyway, I agree, I hate AIM almost nearly as equal. Also, when I'm feeling kinda anti-social, AIM pisses me off because people I don't really want to talk to my family (aunts,uncles,grandparents). I rarely use it anymore because I figure the only friends I really care about are the close ones to me. If anyone else wanted to contact me, they could just send an e-mail.
