I think news.yc has a 5th troll behavior and it's down modding a comment because they disagree with it. I have been down modded a number of times not for saying something rude or stupid just something that others don't agree with.

I tend to down mod rude and aggressive people on here and I also up mod people who I think have been down modded unfairly.

I am not sure if I am alone with my way of thinking.

I think it's ok to use the up and down arrows to express agreement. Obviously the uparrows aren't only for applauding politeness, so it seems reasonable that the downarrows aren't only for booing rudeness.

It only becomes abuse when people resort to karma bombing: downvoting a lot of comments by one user without reading them in order to subtract maximum karma. Fortunately we now have several levels of software to protect against that.

The only problem is such a system will tend to award popular ideas (or humor) as opposed to unique, albeit possibly controversial ideas. When I go digging into the comments I generally look for two things... a large thread of comments and particular users whose opinions I regard. These are not necessarily, although they often are, the posts with the highest points. Occasionally I find gems near the bottom.
