Just a thought, but is there a need for each tag to have a different color? I understand it makes for a quick way to differentiate topics, but unless you memorize the colors, you'd need to read the tag anyway. It works welll if you browse by subforum, but the multitude of colors makes browsing "What's New" very cluttered looking. What would you think of tying color tags to subforums? Or at least, tying color ranges to subforums?
Also, I think a Politics tag would be good.
