That's all fine :)
However, I have a suggestion for you / maybe even this itch dare … Which I think is a major flaw in Ludum Dare, and will always be, even if PoV manages to prevent abuse of the voting system. It's a double-blind jam:
People create their game anonymously, with no obvious logos, names, etc, and submit it as such. Talking about the specifics of your game before the voting phase is over disqualifies you. After the competition is over it's okay, obviously. In the voting stage, people vote on games, once again, without knowing whose it is. Blogging / talking about interesting finds might be okay to increase visibility? I dunno.
Point is, the names you find as 'winners' of whichever LD are always kinda similar. People come to expect good games from the winners, even if they aren't. The names themselves bring additional visibility. I don't want to sound butthurt (and indeed I can't complain about my placements at all) … But I think this would give everybody a much more balanced and fair chance. I know it takes away a bit of the community involvement … Although maybe the community would try to venture guesses or would be excited to reveal the names when the winners are chosen.
Instead, it's more about serious competition (which is not always best for jams) that is harder to abuse – which might make it more tempting as a contest / attract sponsors?
Just an idea. :)
