I'd argue Nostr isn't ready for people. I care about decentralization a lot, but most people do not care enough to move out of the comfort of personalized content. Until that can be replicated, it's difficult to compete with modern social media.
But of course, I'm optimistic about Nostr's future. I'm currently experimenting with ideas with customizable client-side recommendation algorithms or/and higher level relays with curated content.
