I’m an independent podcaster, and agree with all you say. Sadly, in terrestrial broadcasting, there is a Berlin Wall between public and commercial radio. Podcasting offers a great opportunity to tear down that wall, and allow “both sides” to learn from each other.
Now a shameless commercial plug… my new almost-pub radio podcast co-hosted with my buddy Jim Meigs (ex-editor-in-chief at Popular Mechanics), is How Do We Fix It? Find it on iTunes, Spreaker and at www.howdowefixit.me
