Perhaps some measure of time spent on a piece of content x trust/value score of the content (where user or app can apply whatever trust/value score they want)

Daily users sending or receiving zaps is an easier "objective" measure of actual value creation though and applies to other activity I hope to see more of on nostr (e.g commerce)

Perhaps best overall metrics then might be Nostr GDP, GDP / capita, and total users contributing to GDP daily (sending/receiving zaps or payments)
