I think at least part of it is because the people on HN enjoy solving problems so much. When there's a post that says "we solved this problem", a lot of people here (me included) think "great, what's the next problem to solve". The focus is on "the next problem to solve" more than the "great", sometimes to the degree that the "great" is completely ignored. I don't think this is necessarily a bad thing, but it can get grating. It reminds me a lot of a part of the essay "How to ask questions the smart way"[0] by Eric Raymond:
> Much of what looks like rudeness in hacker circles is not intended to give offence. Rather, it's the product of the direct, cut-through-the-bullshit communications style that is natural to people who are more concerned about solving problems than making others feel warm and fuzzy
It's not quite the same, but it comes from the same cut-through-the-bullshit attitude.
