We caught up with Cory Doctorow at the ETech conference here in San Diego. Cory is co-author of the blog Boing Boing, a digital rights activist, science-fiction writer, and all-around brilliant thinker. We talked about some of the themes that emerged at ETech, including how we can reduce climate change without "putting on hair shirts," how to become great, the wireless wiretapping controversy, and more.
