@Craig @Gabriel But the dynamic is kind of different, don't you think? When you ask to participate in a Branch, it means you have something to say (otherwise you just lurk). Participation in a real-life conversation is much more fluid and implicit.
I think I'd agree with @Michael and argue that the best use case for Branch currently is in "conference" style conversations - where active participates fluctuate but ultimately "own" the stage.
Is the contrast between the dynamic of a conference panel and a "dinner table/bar" conversation enough to demonstrate some of the consequences that invite-only/atp functionality presents?
Thank you for your thoughts, I've had a blast using the service and am waiting for my invite to keep at it!
