I'm a podcasting fiend. Good ones are hard to find and easy to exhaust. I love a good conference podcast, a speakers series, or the Sports Guy's seminal BS Report. Lately, I've received immense enjoyment for Ronald D. Moore's Battlestar Galactica Podcasts. For him, recording the podcasts seems to be a labor of love rather than a chore. I especially enjoy the podcasts accompanied by his wife as well as the inside the business tangents they sometimes veer off into.
The ultimate podcast from the series is a three-hour with his wife and some of the cast members recorded during season three. The back-and-forth is engrossing. Its a conversation I could have listened to for another three hours and I think they could gone for much longer also (although the Scotch may have eventually caught up with them.)
