Hi, my team and I are constructing a new q/a site, and we wanted some input from a Web Design community on what was good and bad about our design. Some issues we've been worrying about are:
1. Too many colors
2. Looks disorganized
3. Usability
The colors dont bother me. I see you are using pastel colors for large areas, which is good.
To help the eye, you can alternate greys on the posts, so they don't look as one and that helps organize. It's a little trickier code, but not too crazy .
