Downvoting on reddit is actually reserved for comments that don't contribute to the conversation and isn't to be used for disagreeing with a comment. Anyway, blaming reddit users for all the negative shit that happens here is seriously getting old.
That's how it's intended to be used on Reddit, sadly it's not really how it's actually used on the larger subreddits. Seeing as Reddit is a big recruiter for HN, it should come as no surprise that reddit user cause a lot of the "negative shit". Of course, they also contribute a lot of positive comments/articles.
