As you can see, the new design is now live. Thank you for your feedback. We have also updated the new look to UX.se's twitter account and its chatroom. I hope the new design will help to attract new UX professionals to the site. Of course, ultimately what matters is the awesome content you all have been creating. Thank you for being a great community!
If you see any CSS/Usability related bugs in the new design, please let me know. Start a new post please, and tag it with "Design" and "Bug."
If you're still seeing the old favicons, please load the follow two URLs in your browser and do a hard refresh:
Once the site stats improve some, I'll remove the "Beta" tag from the logo and make the site official!
