It's OK, I guess. I'm not a big fan of "microsofting" everything with rectangular (50?) shades of grey (or other colorshades), but that seems to be the thing to do now. I also agree with Tony on the blue shade/contrast issue.
What's with the green frame around the gravatars? Was that always green, or did that used to be purple? (So yeah, grown man here, and I like the "Extreme Purple". Don't pull my man card )
That being said, if it's readable, if I find my way around, it'll be fine. Content beats (almost) all.
