As a crypto-skeptic (lol), I really like Nostr. Unfortunately, I don't think it will catch on until someone takes the time to shave off the sharp technical edges and figure out spam + identity verification. The current Nostr network is full of cult-like bitcoin cryptobros, racist Twitter/Fediverse refugees, and spam. Lots, and lots of spam. But the technology is cool af and could be made into something more.
