There is a bit of a bad psychological effect on HNers: don't say things that might get people angry/to disagree, or your Karma goes down. But there is also a good psychological effect as well: don't say stupid things (like "LOL, wut?"), or you'll get down-voted.
Either way you look at it, there's a bit of good and bad in HN.
