This is very cool for making freedom of thought unconditional (local first + encryption + creators keys), but public spaces? They need to be restricted in certain ways, since they affects other people. They can’t be unmoderated. So we need a centralised system?
I agree that public spaces need rules, resolution of conflicts, etc - because as we can see networks are flooded with spam - i think this is the toughest question - how to govern them. Still, one centralised governance for all public spaces looks like not the best solution. I think ideas about more local governance - when for example categories / themes are governed by those who create it
Bluesky using layers for moderation seems very promising to me. Yes you need restriction but no it definitely doesn't have to be centralized.
Bluesky definitely does do their own moderation too on the content they host. But as they federate, the centralized solution becomes obviously insufficient.
