Maybe it was happening before, but I've noticed it a lot in the last few days - every time there is a thread about Elon Musk, it disappears from the front page extremely quickly, regardless of how many upvotes it has (or the speed of them).
I knew Hacker News had built in abilities for their moderators to promote and suppress content, but I am very surprised at the topic/consistency of this suppression in this instance. What gives?
If you want more explanation, I answered a similar question the other day: https://news.ycombinator.com/item?id=33992824 - though more in a cri de coeur style.
Btw, none of this is new—it happens every time there's a major ongoing topic with divisive qualities. The principles we use are: (1) downweight the follow-ups so there isn't too much repetition; (2) upweight (not a word - I just mean turn off user flags and software penalties) the ones that have significant new information*; and (3) downweight the hopeless flamewars, where the community is incapable of curious conversation and people are just bashing things they hate (or rather, bashing each other in the name of things they hate).
The most important is #3, because it's about preserving the ecosystem. We want HN to live another day. No thread is worth more than that, despite how huge and existential these stories always feel.
If HN were an art house theater, those principles would look like this: (1) don't show the copycat movies; (2) do show the interesting movies; (3) when the theater catches fire, stop the movie and deal with the fire.
