Things move in waves, not a straight line, but I'll admit that I haven't been thinking about the grand visions of a nostr powered future very much recently.
This will probably remain a niche community with a certain set of interests unless we can solve some structural issues and catch a lucky break. The game theory of social networks is not as straight forward as it is with money.
But with that said, I still use nostr for 90% of my online interactions and am not an active poster anywhere else. Bitcoiners are a stubborn bunch and this platform serves me very well for the type of social media experience I'm looking for.
