Please don't post unsubstantive dismissals of others' work to HN.

If you know more than the rest of us, it would be good to post an informative comment that teaches the reader something. If you don't want to do that, it's fine to post nothing.

If you feel that something is trivial and potentially wasting other people's time by means of wasting pixels, I think it's fine to speak up. (Explaining why something is trivial may not be that effective, in general).

I was clearly wrong in that many people disagreed and found this to be an interesting and nontrivial subject.
