HN is such a weird place. Every so often it adopts these communities of people obsessed with something, and lately it's whatever LK-99 is. I wish they'd just go make a subreddit.
I find it much more odd that whenever noteworthy scientific or technical news are heavily discussed on this news platform that is pretty much for such content, some users are very quick to be needlessly dismissive of everybody's interest, citing the currently higher frequency of threads/links concerning said newsworthy topic.
Quite ironically though, individually policing & complaining about the relevance of specific subtopics indeed feels quite "Reddit", while one of the things that make HN so pleasant is exactly that it's user base usually abstains from arguing about such meta & leave moderating actual offtopic to the moderators.

And some people's personality is to be an armchair expert speculating for speculation's sake. I guess it makes them feel smart, and they like to hear themselves talk
