Interesting thoughts in this thread but imo it includes some critical misunderstandings. 

1) nostr is a protocol, not a platform. This is important as it changes how UX(D) works. It changes how  social-behavioral patterns emerge, because it’s different things to different people. It looks and works differently based on what client you use. 

2) V4V doesn’t propose an artist can live off art posted on something which is in its early beginnings with 40k active weekly users. Especially arts, music etc. follow a power law. As a result network effects need to be much much bigger for this to work. The general assumption of V4V holds true though. Users not only zap contents they like but they zap people too. Albeit for different reasons, sometimes just to zap for the zaps sake. 

3) it’s not that traditional social media platforms design UX to trigger stronger dopaminergic reactions. It’s more like people do it themselves, platforms recognize the patterns and build on top of that them to capitalize on it. They artificially enhance a natural bad pattern so to say. Nostr will be a dopaminergic experience or it will die out due to utter boredom. The challenge is not to suppress this but to make it meaningful and balanced.
