Yeah, probably. Nostr is quite hated by the Hacker News community from what I have observed. This is most likely because it's used by folks that are into freedom technologies that explicitly don't allow excluding any users from participating. And so it attracts people that are into bitcoin, Tor, cryptography, etc. "Crypto" is actually quite hated at Nostr and you get called out for bringing any stupid crypto coins. You are free to talk about anything though and the system can't block or exclude you, but people may mute you in their clients.

It’s not really crypto adjacent. It is full of Bitcoin maxis who vehemently hate crypto though.
