What podcasts do you listen to?
drjrock: RadioLab (http://radiolab.org) is simply the best podcast ever created ever.  Other than that, I listen to This American Life (http://www.thisamericanlife.org/) for serious stuff and You Look Nice Today (http://youlooknicetoday.com/) for comedy.  And for a little shameless self promotion, check out the Rails Envy podcast (http://railsenvy.com) for ruby/rails news.
