I would worry about relays being too permissive to low-signal authors and bots. But then again, if it's about ideas, bots should be totally ok, too. Hmmm...

Moderated relays are platforms. I'm on nostr to use and seek protocol solutions not platforms with alternative clients.

The content has to live somewhere, it doesn't have to exist in one place... but it's cool, I didn't mean to step into the middle of some argument. I intended to share, with the axiom, that the main community relay does host threads. That's all. Sorry.
