what if there was an activity type called Message and you didn’t need to wrap it in a Create
id: ... actor: alice type: Message to: bob content: hello bob
as expressed above it is intransitive, but you could also Message a room or conversation of some sort?
id: ... actor: https://alice.social type: Message object: https://alice.social/conversations/1 to: https://bob.social content: hello bob
id: ... actor: https://alice.social type: Message object: https://alice.social/rooms/1 to: https://alice.social/rooms/1/audience content: hello world
