I think what we really need for Nostr adoption is to purple-pill influential folks in other niches. The closer those niches are to bitcoin the better, such as AnCaps, 3D printing, hard money advocates, etc.
Ideally, someone like @Snowden should be able to bring a large bunch of online security folks over to Nostr, as long as we give them a great experience when they 1st arrive.
Is anything still missing from major client apps that would give them a better experience?
