What if we had a user-experience over a Fediverse "Group" (i.e., ActivtyPub Actor type "Group") that looked more like a group-chat.
I mocked up a desktop style UI for it.
(A mobile UI would be more condensed.)
...
For FediCon I used Signal for group-chat. But I would have preferred to keep the conversation on the Fediverse. And, if a UI like this existed, I would have been able to do so.
