Nostr Protocol + Mastodon API - Interop via Ditto

I'm very excited about this development.  It has the potential to be
ActivityPub done right (or at least better), with full nostr integration:

"Our new project, "Ditto", is a competitor to Mastodon. It is an
open-source, self-hosted social media server for online communities. While
it borrows many ideas from Mastodon (including its API), it is built on the
Nostr protocol. Ditto brings the best parts of Mastodon to Nostr, including
dozens of native apps, and several new features not normally available on
Nostr."
