Although Nostr was not specifically designed for private notes, its relay model is most suitable for them. Additionally, compared to public notes, private notes face less censorship because they are encrypted. Private notes require less from Nostr's design.
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 (nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn, 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?

are you in touch with nostr:npub1zuuajd7u3sx8xu92yav9jwxpr839cs0kc3q6t56vd5u9q033xmhsk6c2uc on his latest? i need to catch up to learn more, but it’s a nostr private messaging project aiming at fixing some problems that the current ecosystem of nostr DMs has
I know he is writing a nip about signal protocol.
