I think it helps having guidelines and not relying on user sentiment alone. When I first joined HN I read the guidelines and it did make me alter my comments a bit. Hoping everyone who joins goes back to review the up/down votes on their comments and then take away the right lesson with limited information as to why those votes were received seems like wishful thinking. For those who do question why they keep getting downvoted, it might lead them to check the guidelines and finding the right supporting information would be useful.

A lot of the guidelines are about avoiding comments that aren’t interesting. A copy/paste from an LLM isn’t interesting.
