Great find, thank you. I've wondered for awhile what the posting guidelines are there and these make so much sense. I wonder if Paul Graham wrote them. I love everything he writes.
It makes me ponder curation even more. It feels like most things start as free speech and then go through a process of becoming more curated. Wikipedia doesn't have conspiracy theories about vaccinations because it became more curated. The Apple App Store, Amazon book reviews, The New York Times comment section, Apple News. Even Reddit is becoming more curated. They have all become immensely popular as they've gone down the curation path.
