Looking at the URL has me thinking that this confusion would be resolved if HN adds a small piece of logic to treat the domain publish.obsidian.md specially, just like how HN already does for pages served under forbes.com/sites which is not written by the Forbes staff themselves.

So instead of showing the domain as obsidian.md, HN would show the domain for this link as publish.obsidian.md

Maybe something for dang to consider if he sees this comment?

Same thought here. Why would Obsidian bother with AI? Oh wait, this is publish? So this is what $8 per month gets you? I am amazed, as I would have at least expected a subhost: [username].publish.obsidian.md
