I think It's a chicken and egg problem
If bitcoin is understood and adopted by everyone, nostr adoption will be easier as everyone appreciate zap
Hence Migrating content creators from other platforms will be a challenge, because they first have to appreciate Bitcoin as value transfer. And. Zaps culture need to be big enough to be able to surpass ads revenue for content creator to want to move here.
Otherwise I feel nostr will continue to be for niche segment only
Like it or not perhaps nostr need a client that have algorithms for trending/popular post as that is the thing content creator relies on to maximize their revenue stream and continue to create content
