Turn the radio on, turn the radio up -- Good stories for podficcing

[zvi]

What sort of characteristics make a story good for podficcing? Are there any specific writing techniques that make it easier to record? Or what about making it easier to listen to? Are there specific characters who, when listening to a story from their POV, make it easier to fall into the story? Are there any authors that you'd point a new reader toward because they're really achievable?

I'd love to hear about either specific techniques or, if you can't isolate the techniques but do have excellent examples, please trot those out.
