Nostr is an awesome protocol that surely will have an impact in the coming years. If you don't know, you can read a basic intro to Nostr here.

People like Jack Dorsey and Edward Snowden are already there (I know they are somewhat hated around here for particular reasons), but they have a big influence.

There are already appearing paid relays, for which you pay a small fee through LN and you get access to them. Also, LN payments are already integrated in most clients.

Maybe a client could integrate XMR payments or a relay could accept XMR.

I think it can only benefit the community to have presence there.
