I have been sampling philosophy oriented podcasts lately and found one that strongly strikes a cord with me. Derek and Swoopy started their show, Skepticality, in 2005 and have interviewed a broad range of sceptical guests. There is a galaxy (star cluster, at least) of activity and discussion on these topics that I will link to as I discover them. The title Skeptic encompasses individuals and groups that include atheists, humanists, freethinkers other nontheistics that in general expect a little proof with their pudding.
