I'm on nostr to keep up to speed on the relay tech, which is solid, but the best use cases for it are outside of the social network context (B2B stuff). Random conversations keep me motivated to come back for tech updates.
Numbers matter a lot for social networks. Without them these networks can't be sustained. Nostr is bleeding like $1m per month. A network can't be free and bleeding money at the same time. That's just putting freedom on the credit card, the bill will come due.
Also agree it should be cryptocurrency neutral, though not sure how that works in practice.
