Recently, since my bike is in the shop, I have been walking/riding my bike to work. To amuse myself I have been listening to the Cory Doctorow reading of Bruce Sterling's (blog)"The Hacker Crackdown". I got an iPod shuffle to have something I feel comfortable carrying around. In pursuit of more to listen to, I came across LibriVox. LibriVox is a free, volunteer based AudioBook service that provides public domain audio books.
