My good friend Steve Stewart did a presentation on how a podcast can boost your business. Steve is the editor of Podertainment magazine, the author of the Yes You Can Podcast Too blog, and produces a great personal finance podcast called MoneyPlan SOS (give it a listen). His presentation has great information, and a great flow. That's because Steve can also teach you how to use Screen Flow (a great presentation software for the Mac).
