I don't know how to feel about this to be honest. On one hand I think that this is fascinating, on the other I just don't engage with ads and use adblockers on all my devices, including DNS based ad blocking, so I personally just ignore ads. And I'm not sure if being paid to be subjected to ads is a much better model, it's better but not much better.

To me the real way for people to earn money on nostr is Value4Value, by zapping posts you find valuable you can send a message to the world that you'd like to see more of that.
