I like and appreciate your explanation. I get something new every time I ask the question and learn more each time. My concern is that Nostr might become a broadcast station playing to empty cities, where valuable messages go unheard, and the name "Nostr" fades into oblivion. Any potential to make a difference could be lost. I understand your perspective and believe it could work. It reminds me of the "If you build it, they will come" mentality. I hope they do.

Ultimately, why not both?!
The beauty of division of labor is that we don't all need to have the same strategy, anyone can try out anything, and something will eventually stick.
You can for example post screenshots of the exclusive notes on twitter, highlighting how cool it is over here, and that this content isn't published directly over there.
