I settled on Google Groups because I am old fashion and prefer listserv-like functionality. It has a good archive setup that looks and works much like Gmail’s web interface. It has file hosting and primitive page creation and management that may come in handy, too.
The group is here. If you prefer not to register with Google, send me your email address and I will directly add you.
I intend to share future interviewees to open up the development of questions, as well as future topics and segments. Also, everyone should feel free to post questions and corrections on any past show content.
