I just wanted to do a quick plug today for the Writing Excuses podcasts by Brandon Sanderson, Howard Tayler, and Dan Wells. If you've never listened to one of these, you need to. They've been podcasting for a few years and you can find a podcast on most writing topics. Each episode is 15 minutes long (because you're in a hurry, and we're not that smart) <--their tagline. I love it.
