The New Media School is dedicated to helping you understand audio and video podcasting, as well as other new media tools.
If you come away from this site with nothing else, come away with the understanding that all this technology is just a means to reach your audience. The goal is to inform, to entertain, and to start conversations. This is digital storytelling. What you learn here is no different than cave painting, except that it has larger reach, and repeatability.
As a potential podcaster, this is one site I'll visit before going to PodCamp Boston.
If you have considerd podcasting, and have not done so yet, then this is one place to visit.
If you are an experienced podcaster, then this is also a place to visit and potentially help by sharing what you know.
Either way, add it to your RSS reader of choice and keep informed!
