there needs to be three layers

secret, private and public

public discussions need to be blastr - no, blossom, in fact!

private discussions (eg communities) need outbox

secret (between two) need a rekeying scheme and a HD keychain

i think if you all let that percolate through your brainboxes for a while you'll see that this is a key distinction that would make architecture of nostr so much simpler to understand
