After getting back from a lecture at the most recent N-TEN Tech club meeting, I found myself enlightend as to the way of the podcast. Brian Russell is a stand-up guy doing a lot of grunt work with the development of podcasting as a tool of activist. His website does a great job of explaining the current state of the field, and of course his podcast is great: www.audioactivism.com If you are completely new to podcasting, a quick shot in the arm: http://en.wikipedia.org/wiki/Podcasting
