(sliding votes) - Yes, exactly! The thing that bothered me the most was that given a hypothetical vote of 3 keep, 25 delete, we'd end up keeping the post even though most people thought deleting it was the "right" thing to do. I think a sliding vote type system would resolve that issue, yet ensure that excessive reaping wouldn't become a bigger problem.
I think 2 keep votes is enough that nothing automatic should happen. What we need is a system to allow manual reaping other than pestering a god to force-reap. I'd hate to see that keep limit become variable.
