We now have a question that's really, really popular, Why do programmers write applications and then make them free?, which is fine (better than fine, great!), but the color used for the "on fire" state overpowers the rest of the color palette, drawing attention to the question over everything else:
Could the red be subdued a little so it's not as striking?
(This is also a problem on comments with a ton of up-votes, but not as big of an issue as comments don't appear on a page everyone visits. Presumably they share the same styling rules, though)
