Just posting this so people can easily take a look at how the competition is being structured, so nobody has to wade through that long thread with the poll discussion.
So, in Aaron's own words:
For the competition we will be voting on two brackets per week for the first round. The high scores that move on to the second round will then go through a second voting process, which will bring us our top six for round three. Round three is the face-off round. Each book in that round will face off in polls against every other book in the round. The winner of each poll will receive a point for their win. This will determine our final results and give us our winners.
