Quantitative Analysis brings you... Ravenclaw wins!
On LJ, the drabbles were submitted as replies to comments. I don't know how to link to those. However, they are conveniently on fanfiction.net in my complete drabble collection, and those chapter links are listed in THIS post..
Click HERE for the competition guidelines, point system, and rules. Click HERE for the results page, which shows that:
1) Ravenclaw had 45 points, while Slytherin had 33 points and Gryffindor had 9.
2) Ravenclaw was a one woman team, while Slytherin had three players and Gryffindor two.
Oh yeah, and it seems worth mentioning that this competition was quantity-based, not quality-based.
