New Podcast

I have an Idea for a new podcast but i need all your guys' input. I think the review podcasts are good and interesting, but what about a story podcast. kind of like the radio shows were. What I need from you, besides what you think of this idea, are some ideas of what to do as the subject for the podcast-show. Setting, should it be a mystery, comedy, etc..., or even the name and nature of characters. Thanks for the help just post your comments in the comments section of course.
