What I know NOTHING about is what to do with it afterwards, and what the expectations of people hearing podcasts ARE. I don't listen to them myself -- I never got into talk radio stuff and I can't listen to people reading books on tape -- but I know a lot of people do, so I need to have some idea of what people expect.
My plan is to read my books, a chapter or two per podcast, and maybe intersperse with particular facts or anecdotes about each sequence in the book (for instance, in Grand Central Arena I would mention that the protagonist's full name, Ariane Stephanie Austin, is a reference to Steve Austin, the Six Million Dollar Man).
Is this a reasonable general plan? Do people listening to podcasts expect to hear something other than voices (background music, etc.)?
What format do I have to save the final audio files in for use as a podcast?
Would it be a good idea to turn them into Youtube presentations with some relevant still images (for example, showing the map of Zarathan and zooming in on the location for the current chapter)?
