My new job involves a significant commute. In search of ways to make good use of my drive time, I came across the Writing Excuses Podcast. These podcasts are done by authors Mary Robinette Kowal, Brandon Sanderson, Dan Wells, and Howard Tayler. If you haven't already, you should check this out. They talk about a variety of subjects and provide useful insights, for writers of any genre, not just sci-fi/fantasy.
Do you have any writing podcasts you would recommend?
