I'm liking that you've had a play with changing buttons etc but (and I know you've changed them a bit) the table colours all look a little...default... to me. maybe you could change them for a colour scheme with the background or something?
While I do agree with the bit about the colors, I didn't really stay as long as I'd like ... I can't get sucked into a discussion of AI while at work!
Guess that says what I think about the content.
Might want to think of adding either some blogs or some sort of an article system as your next mod. Also, from a design perspective, you might want to left-align your links et al in the header and butt them up against the logo... but that's my biggest bugaboo about the default Snitz design anyway, so take it for what its worth.
