There's always a flavor of the month. Go back 3-5 years and every third post was crypto or NFT related. AI/LLM too will pass.
I've never really understood this desire of people to effectively hide content that doesn't interest them. Just... ignore it. Like there are enough people on HN who really care about academia and research. I don't. But that's fine. Let them be.
But here's the interesting part: so many on HN rail against the newsfeed concept . You will hear a significant number of HNers say they just want everything in chronological order. Well, except for the subjects that don't interest them.
If HN submissions were tagged and a recommendation algorithm decided what to show you, you'd get exactly what you want: fewer AI/LLM posts if that doesn't interest you. But somehow newsfeeds are still bad?
