You could post on X daily telling the X folk that:

You are on the Nostr protocol and giving your npub address

Nostr stands for Notes and Other Stuff Transmitted by Relays

Nostr protocol is decentralised and includes things like Social Media, Chats, Livestreams etc etc. They should checkout https://nostrapps.com/

They should check out clients such as Damus, Primal ete etc on the different iOSs

Nostr enables bitcoin zapping

Great people are also on Nostr such a Jack, Isa, TFTC etc etc

Just thoughts.
