Some policy/feature/system to aggregate related stories ("killing" stories that duplicate stories that already have active threads, and posting a link to the "duplicate" story in that thread, or something similar to that --- I'm being minimalist here).

A lot of dumb comments appear to germinate on threads that are the 3rd or 4th take on some tech news story about Facebook or Apple.

To me, this is the biggest problem with HN rather than comment quality. Tons of related, and even duplicate, stories happen all the time which fragments discussion. Not to mention the duplicate posts which happen a few months later. Thankfully someone usually remembers and posts a link to the previous discussion but that shouldn't be required.
