so by my definition of a "nostr node" the damus notification relay technically isn't a nostr node, since there's no way to sync notes between it and yours. maybe nostr node = node that understands nip77 could be one definition.

this could enable nostr to be more like a p2p network in the future with the right overlay network, with nodes syncing with each other via negentropy. me and martti and a few others have been thinking about this.
