Sounds like a great idea. I would love to see this, and I think it would be a great model for new users to follow in their future discussions. I'm guessing it'll be a sticky? Reading over the scoring and looking at that link reminded of the good ole' times when I used to be a high school debater. I think there should be a limit on content length (2200 or so chars for opening, 1200 or so for rebuttals) as well. Then the 10 posters will be forced to optimize their arguments, and will be deterred from any redundancy in posts.
