The beautiful thing about podcasting is it's just talking. It can be funny, or it can be terrifying. It can be sweet. It can be obnoxious. It almost has no definitive form. In that sense it's one of the best ways to explore an idea, and certainly much less limiting than trying to express the same idea in stand up comedy. For some ideas stand up is best, but it's really, really nice to have podcasts as well.
