It sounds pseudo-englightening without any substance. Ok, you've observed this meta aspect of HN. So, what?
I agree that it's not a very deep observation, or maybe even not true. But it 1) seems to explain several different reactions I see on Hacker News, and 2) it illustrates a trap that I, as a Hacker News user, find myself falling into without realizing: the belief that the thing I want is the thing that other people want. To me, it's good to be aware of that.
