You should be able to vote down bad stories. I thought this wouldn't be needed but we're starting to get off-topic submissions, so we need to be able to bury them.
Maybe the rules could even be tweaked to keep good stories with a minority viewpoint from being buried. At the very least, maybe have down votes count as only 1/2 a vote. (So there would have to be greater than 2:1 of people against a story to bring it down below 0 points)
