If you're thinking about dipping your toes into the waters of podcasting you might enjoy this podcast (audio show). It's an interview that Sarah Rourke did with me about the podcasts I've started to do at Confident Writing
You can listen to the interview here - the link takes you to an MP3 which you can play on the computer or download and play later if you're set up for such things. It's just over 15 minutes long and is mainly about ways to get over any barriers to getting started.
Sarah (also known as the Rat Race Escape Artist) has set up a service to help you with podcasting and other audio services. You'll find out more at her new site The Audio Pod Artist.
