Wow, I think my experience has been different. Redditors seem to pile on a 'wrong' opinion and downvote to oblivion, whereas HN seems more evenhanded to me. I'm sure it depends on the subreddit though.

Reddit does not pœnalize one for downvotes to the same extent.

On Reddit, if one's all time score be negative, one is throttled to one post per 10 minutes.

H.N. throttles to five posts per day if one's recent comments are negative I believe the number is that I've read.
