Ditto currently is inspired by the Fediverse. It's essentially a "port" of the Fediverse experience to Nostr.

So it's based around domains. But there are barriers.

I want to make it so each Ditto server has a "main group". But it also has smaller groups. Different server's "main group" are small groups on other servers. The main group can moderate any small group, or designate another NIP-29 relay to do it.
