Promoting Podcasts. Just MHO:
Shorter works better (for me). 20 minutes? Just a guess - I'm no radio pro. Less time downloading, listen right at the time you find it (cuz you don't have to wait too long to get the thing over a slow connection w/interruptions). Want high density info value (cuz life is often pretty full). But shorter is more work for you cuz you gotta slash w/that blue pencil (or whatever that is w/audio); but maybe editing s/b delegated (like a publisher's editor for a writer) and you get to hear what's left of your beautiful masterpiece and weep b4 it gets ul'd. Bit hard on you, but...
What's your favorite listening among the more popular talk shows? Terry Gross? The Motley Fool? Commonwealth Club? Philosophy Talk? City Visions?
Jack Spirko? Anything there you'd want to shamelessly copy to add attractant to your pods? <g> Come to think of it, IIRC an truly fantastic example of audio reporting/teaching art was created by This American Life a couple years ago; in 2 or 3 shows they explained the impenetrable reasons beneath the economic crash to the rest of us. It was not entertainment but almost purely education.
Then of course, there's gaming Google... Don't even want to think about what that takes. <g>
