On reflection, I don't think the blunt --- nice scale is serving us very well at all. You see me endorsing some elements of "blunt" styles that are definitely negative, and I see you endorsing some elements of "nice" styles that are definitely negative. Neither of us are actually endorsing the negative elements, we're just accidentally including them because our language is too imprecise. I think.

LessWrong has adopted some elements of bluntness because those elements serve the community well. Some of the elements would not serve us well in other social settings. When someone points out in a top-level post that this is the case, those who already know this instead see them suggesting that LessWrong should abandon these elements of bluntness.
