Hey @hodlbod
Listened to your interview on Bitcoin And... yesterday. Great stuff sir and gave me loads of homework to do.
Questions: Is there utility in approaching nostr as a potential for "closed" communities? I recall you mentioning a scenario where you and a friend might share the same set of notes... but could that be scaled to maybe 50 friend and family identies with access, 500 tuition-paid students, or 5,000 employees, etc.?
