I just listened to the interview and it was good to hear Marc's voice. What an interesting topic. I haven't followed all the links above but it certainly has piqued my curiosity. The health consequences in particular interested me.

This format certainly holds a lot of promise as it develops. I hope there will be ways to make it more interactive as well.

Can I ask that you all post a linky to the Center for Emerging Media here on the blog? I understand that the website is going to be renovated, but I think it would still be useful.
