There will be no theme competition using Summer of Code money, as previously advertised. The fate of SoC money will be in the hands of the Drupal association when it comes into being.
Theme site set up
There is set up a small testing site for themes at http://theme.drupaler.net/.
I've tried to install all available themes (4.7.2) and categorized them according to their validatation against "Markup", "CSS" and "WCAG".
All Installed themes can be easily tested from a "Test [$theme]" link. If you are registered you are able to vote for a theme.
If a theme is missing, you should post a story with the [$theme].tar.gz
CSS Error & Warning free: ! or ?
As I've started "W3C compliant CSS"-issue (http://drupal.org/node/70296) as a wish, it was the first one in the chain of validitaion.
The main critism of warning-free css-validation is the "inherit" argument, which changes nothing visible, but is needed by W3C-validation (warning free).
In my opinion there is a difference between an "explicit defined default" and an "undefined default", cause the "explicit defined" says: Yes, I'm sure, that I want to do this.
As we are experienced webusers, we know that the warning of "undefined color" doesn't make visible sense. But it's one of my most-hated questions customers asks me twice a month: "Why does your site so much validation warnings, although you are working active for accessibility?".
