Well because down voting influences karma I'm probably posting 70% less than I would. I see HN more like a news site in which I sometimes share my view on something but not to comment or to discuss something (sadly). First I saw HN as something to have an intelligent discussion, but after a few "controversial" posts, and having negative karma, I don't bother. I only post something when I think it's "safe" to post, or when I have time to write a detailed essay. I think some people can have an intelligent discussion on HN, not for me, maybe because of my dyslexia I'm bad with words. But then again, maybe that's the price to pay to keep the trolls away.
