Hi,

The voting/XP is just right I think. The chatterbox is nice, but it deserver a own page I think.
Sometimes it's hard to find the different subjects and maybe some other lay-outing could be used...
What I mean is I like to see everything at 1 glance. Sometimes I got the feeling not everything looks and feels in place.
It's better to visualize things: like the replies on the replies this could be more visual so you could see right away it's comment on a reply.

If you want some more pointers ask me, I'm a webmaster of proffesion.
