Bravo! This is a powerful idea that's already been successfully piloted; it's easy to see how it can become even stronger by being internationalized. It has to be -- sustainability is a global challenge. The only thing I'm unclear about is whether there's an explicit message or idea behind each story....or is the message for the listener to fill in? (I suppose the impact of the stories would be lessened if they became too preachy.)
I very much like the vision. It seems to me that the missing piece is how to turn the "performance journalism" into true conversations -- back-and-forth communication that takes ideas and people to new and unexpected places.
