Nostr is good at resisting suppression of public messages
It’s not really designed to be a great private messenger/DM architecture
I know some people were working on better DM stuff on nostr (hodlbod (npub1jlr…ynqn), others?)
Then there are different architectures/ideas like SimpleX, Keet, and maybe KeyChat coming soon.
What are the best DM/messaging tools today that fully open source, secure, and private?
