nostr is a fabric rather than the hub architecture that emerged from www.

If I could use nostr to see when my mutual follows are listening (online), then I could initiate p2p webRTC sessions without a server.

nostr seems much closer to how the internet was originally intended to be used during DARPANET development than the direction it took under www era.

nostr really isn’t web3.0 or web4.0 it’s an entirely adjacent web to the world wide web. One with a fundamentally different architecture.
