I guess it's just you. I'm on it with no problems (other than that annoying adverstisment >_< ). It has happened to me before where it would log on and my buddy list was completely empty (showing 0/0) and sometimes it would not let me on at all. I just waited for a while (more than an hour) and i was able to get back on again.
talking on it right now... but i'm using iChat vvvvv i think the jesus dances great, his buddy isn't so bad either
Its been down all day. I just tried AIM client as well, no luck. Aim express is working though, ughh.
