Speaking of podcasts, Ira Glass, the talented host/reporter/producer/storyteller of This American Life, did an interview a while back on storytelling.
He talks about the basics of storytelling, what makes a good story a good story, and how you can ruin a good story with bad telling. He also expounds on how he got started in radio storytelling, what are some of the challenges a beginner has to overcome, how to get better at storytelling, how to find your voice, and how to cut yourself some slack when you are starting out.
