@Sequoia - Podcasting is a pretty simple process which is part of its appeal. Anyone can do it, all you need is a microphone and some basic podcasting software, like Audacity which is free. Microphones can be as cheap as $10. Of course if you want higher end production you'll have to spend more, perhaps investing in a headset and a pop filter.
For people looking to get into podcasts, I'd recommend the NPR podcast directory, which covers such a wide range of subjects you're bound to find something of interest. Podcasts are great for your morning trip to work or while you're exercising and once you're hooked there's no looking back.
