#yaics reminds me quite a bit of #pumpa. Probably because they're both QT applications that load message timelines. I love both.
Only annoyance with #yaics right now is that conversations appear to be in "reverse" order/top posted (oldest at the bottom). Something I can definitely live with.
I'm enjoying #yaics much more than #choqok. I like it about as much as #heybuddy, though I have to hack that one to get it to function.
