To be honest, I suspect it's about the people involved at the moment. There's a lot I like about Nostr but I don't see that it's currently doing any different which would mitigate the perverse incentives which poison regular social media. That said, there seem to be good people involved on the development side of things right now so I have more faith in the future of Nostr than other alt-tech platforms.
There are a lot of Bitcoin people here dreaming big but personally I hope Nostr stays small for as long as possible.
