I'm excited to see where this goes!

I'm curious at the inclusion of ActivityPub.  What role does it play in the stack, do you think, that Nostr doesn't cover? 

 This was the first thing that stood out to me too. Maybe it’s acting as a glorified proxy / endpoint for http ? 

 Also Ditto is an activitypub and nostr bridge in itself. It’s this stack just recursive? 😂
