I've been listening to more podcasts lately because I've been driving longer distances and also riding my bike around the neighborhood. I use my iPhone as my iPod and I download podcasts via iTunes. Some of the ones I like are Fresh Air with Terry Gross and Voices in the Family with Dr Dan Gottlieb and also more techie ones like This Week in Tech, the Google Developer Podcast, and the Java Posse.
However, I recently stumbled upon the Savage Love Podcast through iTunes. It's the audio version of Dan Savage's sex advice column. He has a style that uses four letter words generously which may offend some people so if you're offended hang in there. I think the message is what's important and he does give good advice in his own unique and entertaining style. What I like about the podcast is that most of the calls are really about human relationships and assertive communication. Now an example quote of his entertaining style from a podcast I just listened to, "... There's my advice for you: don't marry him, unless you do, and if you do then it'll be okay, but it probably won't."
