A strength in the sense that other platforms erecting barriers to their data precludes them from acting as a true "town square", leaving that niche open for something like nostr. I expect we'll see an eventual bifurcation of the social landscape into purer, separate implementations of both the private and public spheres, with many hidden invite-only groups on one hand, and on the other hand a single public global context (hopefully nostr).

Like AI is going to scape everything that's not totally private/encrypted anyway and so if there's something that isn't strictly private that's probably because you're intending to publish it, so why not maximize its reach?
