Perhaps you should try viewing comments in light of how it impacts the community at large? I think its good practice to avoid adding noise to a HN discussion.

This leads me to comment very infrequently. If my thoughts were already stated, I stay quiet. If a long discussion has already taken place and its unlikely my comments will be read, I stay quiet. If I post and it gets drowned out by similar comments before receiving any responses, I delete it.

My one and only goal when posting on HN is to add value. If I can't be sure I'm doing that, I don't comment at all. If nothing else, it seems like the polite thing to do.
