I wouldn't say "for" so much as "best suited for"

I think it is a mistake for anyone to use it to build a brand, chiefly. The alternative is something more like email, something mostly for interpersonal communications, less for mass broadcast Tthough mailing lists do exist, and newsletters, I posit they are grafted on, a special use case, not the main one. I think nostr is a really resilient way to do one to a few rather than one to many or one to all style communications.

I'd like to see a nostr future where each relay was more or less independent of the others, or maybe a neighborhood of associated relays, rather than these big, disordered, firhose collections of "PV :shakabra:" positivity posting etc etc
