I really like the idea of the awards-show-style format, since it allows several maps to be recognized for what they did. It's still probably worth keeping in the 1st/2nd/3rd overall prizes, but I like the category idea (as well as the deadline idea - contest starts in January, ends in December). The only worry I have is that we'd end up with a truckload of entries, and the judging period would end up being multiple months.
