One of the “features” that I enjoy about Nostr is the lack of editing and deleting notes (yes, you can delete if the client supports it but there are no guarantees it will be deleted). I think it makes interactions more authentic and more thought goes into notes because, like in real life, you have to take responsibility for what you say. You can’t just delete/edit and pretend it was never said.
This is how verbal communications work in real life. Verbal "notes" get instantly deleted.
