I'm glad to see someone else recognize this.

My current thought is that Nostr is sort of stuck in the 80s (cf. Usenet, the original social media). After the first HTML browsers were invented in the early 90s, the internet became usable for almost anything and Usenet faded into obscurity.

I'm not saying that Nostr needs a literal browser (though I suppose that might be enough), but social media is undoubtedly the worst use-case for Nostr.
