A better question is can any twitter sized social network survive off of (out of "consensus") with nostr?

As to monetization, two-sided-marketplaces is the big one, specifically, reputation management on relays will be the big money maker as it relies on costly signaling. I also expect this may onboard the masses to bitcoin and bring about hyperbitcoinization.

The carpenters, drivers, shoppers, artisans, painters, electricians, chefs, etc. around the world who will provide goods/services over nostr will be the ones getting paid in and adopting bitcoin, which is much better than Cantillionaire-led adoption.

I know, you probably think I'm insane, let's check back in a year.
