I dont know about the social aspects since I don't live there, but as far as AI goes, it's not just HN. There is no place where you get balanced takes that match the work that we actually do day to day. I suspect part of this is accelerated by the media practices of the hyperscalers like anthropic and openai - they make doomerism super profitable for publishers. One of the most natural emergent counterweights to doomerism is over-skepticism. That is my theory for why it is the way it is. The remaining over-hype is a counterweight to this over-skepticism (I'm not talking about altman hyping his business, I mean the general tech people going around bashing sutton and lecun and mentioning "AGI")

Even publications, semianalysis is the only major, decent one in my experience (excluding personal blogs).

Everything is low SNR for AI - have you seen ICML/ICLR/NeurIPS recently?? There is almost no point even going except for meeting people which we do by scheduling talks back and forth every few months anyways.

I also find IRL, then a carefully curated twitter timeline with the politics toggle on the settings page set to off, are the only ways to get high SNR information about AI.

I also feel it's topic-based. On general systems engineering, think databases, OS, architecture, webtech, the SNR on this site is generally amazing. But these days those articles are fewer than before. For example, 2 years back when every other article was about sqlite and postgres, while it was a very unidimensional few months, you could learn a lot from here.
