There's the dichotomy of the walled garden, how to minimize scraping/bots/inauthentic amplification etc. Is a town square a town square if you can't hear what's going on from the public lawn on the edge of the square? I feel like HN does a better job, and the ecosystem of external views, LLM/human summary, HN search etc. Is quite exciting! but the scale between the two is one factor and the moderation we accept here also comes with a constraint on topics discussed and restrictions on speech (tradeoffs that I feel are worth it in our context here) So worlds apart and yet adjacent!
