@LunaDragofelis @evan I think we have two different mental models about discussions on Mastodon (and social media more generally). And different people use different mental models, yet often assume everyone else sees things the way they do..
One model sees a “thread” or a “discussion” as belonging to the person who created the first note and sees subsequent reply notes linked to the thread as being part of Alice’s (the original note’s author) thread. The other model sees a thread as a collection of individual notes, linked together, with each reply note in the discussion belonging to the reply’s author.
In the model where Bob and Carol and Dawn and Eve are just replying to Alice’s thread, one might expect those reply Notes to go to whatever group of people Alice had originally sent her note to. In the model where each author owns their own notes, one would expect reply Notes to honor the audience specified in the reply Note itself.
The confusion is made worse because the audience settings mean different things in different circumstances, and none of the clients are yet showing what those audiences actually mean for any given Note.
