> I think the downvote system here works remarkably well. It's a very big problem to never allow any kind of signal of disagreement or whatever and the system here is intended to keep singal-to-noise ratio high.

It certainly is not, one can verbally signal one's disagreement with a reply. I very much do not believe that it has anything to do with “signal” and “noise” which of itself are rather vague terms and I find that very often people will consider something “signal” simply because they already agreed with it before they read it.

I see no reason for comments to be “rated”, and I certainly see no reason to pœnalize users for lowly rated comments as I see plenty of them that otherwise provide an interesting perspective.

> You need mechanisms for helping people learn "This is not welcome on HN. This is not how we do things here." to try to keep Eternal September down to a dull roar so HN can do what HN does better than any other forum I have ever seen, which is why I hang here so much even though it's never been an easy thing for me to be here.

“This is not welcome.” means “Ðo not disagree with what the nonrepræsentative portion of H.N. that votes thinks says.” and I stress that it is not repræsentative. — it yields more power to those that are willing to downvote something for mere disagreement and gives lesser to those that would not do so, in my opinion very much the type of person whom one should not yield such power to to decide what is and isn't welcome.
