Kind 11 will win #NIP29 https://nips.nostr.com/29#normal-user-created-events
imho we can reuse kinds 1 for poasts and 1111 replies. the only new kinds the NIP needs are 9 for chat and group/moderation actions. Anyways bullish af on NIP-29.
what if people take the kind 1 and post them in the normal feed?
That's not a problem if it's clear to what relay(s) the kind 1 was targeted. In fact that makes it a discovery mechanism.
how do you make that clear?
Technically: with h-tags. To the user: by building your UI on this premise form the get-go
