The new design just went live, congratulations on the official launch and thank you for your design input!
If you see any CSS/Styling issues, please start a new question for the bug report, and tag it with "Design" and "Bug." It will be a lot easier for me to track new questions than reading the comments replied to this thread. A note for IE6/IE7, while we try to make sure the site is functional for people using older browsers, we don't support them to the point of pixel perfectness.
I typically fix CSS/usability issues asap. As for more subjective styling requests, I tend to let the new design simmer a bit. After having used the Beta Sketchy theme for a few months, it will take a bit of time to get used to the new design.

P.S. I'll be hanging out in the TCS Chat room this week on and off. Feel free to send me feedback there too(although I still prefer bug reports to be posted here on Meta).
