yeah, it's more nuanced than "downvote for disagree" or "downvote only for flagrant hostility". It's clear that some people are using downvotes aggressively, and that needs managed. I actually had a period of time when every comment I posted (no matter what time of day or what topic) received exactly one downvote between 5 and 6 pm in my time zone, as if I'd offended someone and they were retaliating. But I've also seen people post comments that are purely inflammatory with no worthwhile content (along the lines of "[group] is evil", where [group] is mainstream -- not ISIS or Nazis, but like, Republicans or Muslims) that didn't get downvoted. So the issue is more than "too few downvotes" or "too many downvotes". So I try to be part of HN's corrective mechanism. If I see something blatantly inappropriate, I downvote and flag if appropriate. If I see something reasonable that's grayed out, I upvote. If I see something non-gray that I think is of negative value, I downvote, and I hope that if I misjudged it someone else will come along and cancel out my vote.
