I wish I could be omniscient for a few minutes just to know what happened to all the people I've A/S/L'd during childhood. Or maybe I don't want to know - I imagine some of them probably died from old age.
I'm really nostalgic about AIM. I met a lot of really cool people on there, but its time is definitely passed. Luckily having used Pidgin for years will make the transition for gchat or something similar pretty seamless.
Still sad, though.
