I agree: as long as we restrict ourselves to tech stories in which (a) no startup is implicated in any way (lest the thread devolve into litigation of San Francisco real estate prices) and (b) no sharks/jets rivalry exists (rails v node, rust v go, mongo v cassandra), the comments on HN are pretty good.

Every other story has mean, uninformed, badly-written, unproductive comments

I also agree that the stories are the bigger problem.
