I think we've hit what Seth Godin calls "The Dip"
Nostr may never be a replacement for Twitter/X, but it is amazing, and opens up a whole world of possibilities.
I see it as the social / identity / marketplace layer for Bitcoin... and a decentralised communications layer for other apps.
The work on Cashu is a testament to this... Nutzaps, P2PK locking of tokens to npubs show how Nostr can enable decentralized payments.
I can send you sats locked to your identity without you even having a lightning address in your Nostr profile.
We are barely scratching the surface of what Nostr's use cases.
