I'd pay **attention** to it. Could monetize it with ads. I'd also probably pay a thousand sats if it's paywalled instead.

Info for reliable relays would fluctuate in value substantially because of how easy it becomes to copy that information or rediscover it: see what your friends use, post a snapshot of the list, etc., so the value to users would dip down until the company came up with new information that fewer people had or that people would find more valuable on net again. If it does a good job vetting and informing, there will always be new info that some nontrivial number of users will find worth paying for, but it requires this diligence due to the low low cost of duplicating info, to get any substantial revenue.

To additionally keep a **consistent** revenue, advertisements or a consistently cheap and frictionless transaction experience would be necessary to make sure customers keep coming to check. Adding complementary services like nostr onboarding tips or something, adjacent to the relay list as an option, might also increase the likelihood of the service being used by first timers.
