Moreover I think that since these people can't express their nastiness directly, they go and "retaliate" on target websites. I never read comments under the articles linked here because I know they are polluted by a lot of useless noise, so I just read comments here on HN. But it could be interesting to see if nasty comments related to HN, like the ones mentioned by the OP, appear in other places as well (not that we can do anything about it, anyway).
