Why bother declaring a winner? People will vote up entries they particularly like, and the "winners" will be obvious. Take the recent spate of Chatterbox clients. At least three of us were writing some at the same time, and others modified our versions. It quickly became obvious that ZZamboni was the "winner", but I like to think that other (read: my) versions were useful.

I'm not trying to get all happy-feely-why-can't-we-all-win, but I don't think there is a need to delegate responsibility to anyone on this.
