Yes, the Nostr tech is cool and I am trying to get people on the Fediverse to come here but there is not much reason for them to move.
It's not a technology problem. It's a people problem. I seen first-hand over and over that normal people prefer save an centralized speech. They are frightened by speech outside their bubble and will cry out for censorship. happens on nostr all the time.
Nostr people think this is new and exciting tech but it's been done over and over before with tech like XMPP, Matrix, Fediverse, etc. The masses don't want or need it
