I'm Jin, and I'll be working on the designs for the Stack Exchange sites as they graduate from the beta phase. Each site will have its own unique theme that will reflect its topic. However, all sites will share common elements so they feel like they're part of the Stack Exchange family.
Thank you for starting the design discussion early. I found some helpful ideas and links in that post.
This past week I've looked at many Drupal resources out there, including the official Drupal sites. I like the design of Drupal.org. Its clean and simple design works well for a Q&A site like ours.
For the logo I think a variation of the Drupalicon works, because it's universally recognizable by Drupal devs and users. From the history of the logo:
After Drupal was initially developed, thoughts turned to the creation of a logo. Of course the concept would have to include a drop, or water in general.
Since I want to keep the content section of the site minimalist, like Drupal.org's, I think it's appropriate to dress up the header a bit visually for a good balance. A polished logo will be the center piece of the header. Also as a homage to the original logo concept, I'm giving the header a subtle water theme.

As you can see, I'm keeping the overall color scheme simliar to the official Drupal.org, but with our own unique identity.
I'd love to hear your feedback. If there are no major design changes, I'd like to launch this site soon to a graduated Stack Exchange site. So an early congratulations from me!
