It has to be said, Nostr folks are so helpful and positive and encouraging. Much to share, shining lights on so many rabbit holes, stimulating, eye-opening.
I'm sure the tone of any network is set by the earliest adopters and if they refuse to budge on their principles, whoever follows is going to feel that vibe.
It's very obvious with forums that the tone is set by the owner. I was in an industry where the forums were animal houses. Owners setting up threads designed to provoke arguments. I set up a forum, called it a reading room, it got quite busy and I literally never had to moderate a thing. People just came along and saw there was no BS and vacuous lol comments , just great info and obligingly adopted that mode.
