Most people I invite don't understand why they need to join "yet another network". I have had friends join, and I'm waiting to see their posts so I can zap and show them the power of the nostr. I'll just keep waiting.
I think one of the limitations I have is that 99% of my human interaction is online. I very rarely go out with friends, not since 2020. I'll go over to a friends house for dinner, but no large groups. I just don't trust humans. One of the few times I rode the bus I was sick for a week after. So all I can do is put out my ideas and how someone listens.
