I agree with you.

But I also say comment away. Just try to be positive and constructive.

I say a lot here and I try to be insightful. Just as many of my comments are never voted on as are voted up. I only have a tiny handful of comments with 0 or negative score, and most of those were on the snider side of the spectrum. I try not to do that in the first place, but everyone makes mistakes.

On the other hand, I'm sometimes surprised how many upvotes I've gotten on comments that I thought might contradict HN groupthink.

I think the existing system works fine. I worry that the commentary is about to actually decrease in value and timeliness.
