This post was killed because a great many users flagged it. Moderators don't, as a rule, kill any stories that have an active thread. That way those who are interested in the discussion can keep it going. The most we would do is demote an item in rank. There are exceptions to this, but they're so rare I can't remember any. I'm unkilling the post, because I want to reply to some of the moderation questions downthread,…
Is there any reason not to "boost" the original discussion if new ones keep getting pushed to the site? It seems duplicative to allow repeat stories just to keep the discussion going. Better to downrank the dupes and uprank the original one if the discussion is still ongoing enough to draw constant repostings.
Empirically, the HN community has proven to be incapable of discussing certain subjects without immediately turning noxious. Once that happens, it's more than just a technical question of how best to consolidate the threads. The values of the site—intellectual substance and personal civility—are being grossly violated. If we allow that, how can we claim they're the values of the site? And if they're not the values of the site, who on earth would want to stay here?
That is the harder problem. We don't know yet what the long term solution will be, but we're going to keep experimenting until we find one.
[1] As you may have noticed, I've been making a lot of those this week--but they don't work on threads that have completely lost it.
