I can't make any predictions based on the identities of the distinguished members of the #HashOut panel.
The success or failure of this project (being promoted as 'the first talk show conducted over social media' [it is not]) will depend on the distinguished participants and what those folks have to say about the experience after the fact. I myself have no desire to play any role in this, either as "participant" or "lurker."
