Why do threads die?
JacobAldridge: I imagine it was flagged multiple times, and tipped over the flag/vote weight. I'm personally in favour of this system on HN - it may be biased towards threads dying, but I would rather kill some good threads than have a bias that allows off-topic, link-bait etc rising to the top.Of course, I have Show Dead on, so in effect dead threads are just an extra datapoint when I decide whether to read.
