@timbray I was expecting to find in your overview the fact that many interactions/responses are hinted at, but unavailable to people who are added to ongoing conversations.
I don’t know how to describe it. It’s related to the fact that some make their posts available only to thair followers. But when these add new people in response, said people only see a fraction of the thread. It amounts to much noise and frustration.
There isn’t any way I know of to avoid this. "Mute thread" hardly scales.
