Nostr IS a bitcoiner thing. I don’t think onboarding is that hard though. Creating a profile in a #nostr client is easier than creating a user/password pair on any other platform. All you need to save is one string and that’s it basically.
The incentive comes from the content. #nostr is 99% about #bitcoin and how to #grownostr. That’s not a bad thing, not it’s not something that will attract users outside of the bitcoin community.
I wouldn’t call them normies though and that implies bitcoin users are not normal 😁
