ShearsIt seems like SpaceCadet had a pretty good system for gauging map popularity, maybe this could be implemented for decisions for future seasons?
self-selection polls are never a good idea for determining popularity, since people with stronger opinions are more likely to vote and they might all even be random open players who can't play phi maps so they put them at the bottom. you can use them as a guideline and to narrow down which maps to discuss in more detail, but not really more than that
