I take it you aren't showing dead threads? If you look at newer submissions you'll see people voting bad stuff to death. HN is insanely decent at community driven self moderation. Not to knock the mods who put a lot of work into the site of course, but I assume the community's own self-moderation helps some.

"Polluting HN" is more than just the vitriol thats flagged - there are plenty of self-promoting, downright wrong, or comments clearly unrelated to the posted article but comment author gets to segue to their hobby-horse (off-topic discussions are annoyingly frequent, IMO). HN is better than most, but its not immune to being gamed. Once there is a financial incentive for it, it will become more common - see how Twitter turned out after offering monetary incentives for engagements.

I mean, is your post off-topic? It is a tangent. Tangents are cool. You may or may not like one, that is OK.

My comment directly answered parent comment on an issue pertaining to search engines. How is that a tangent or remotely off-topic? This meta-discussion, on the other hand...
