Thanks for the link.. I find that thread kind of fascinating, not because of anything in particular about the original comment, but because somehow the person causing so much trouble managed to convince a large number of HN posters to jump in and try to reason with him. Usually it hasn't progressed so far. I think it helps that somehow he got to this point with hundreds of points in karma and has some to burn.
I was initially a little worried because he was showing signs of being a paranoid schizophrenic, but then I remembered that I was on the Internet and probably shouldn't be surprised.
