I suspect there's a strong overlap between listeners of The Skeptic's Guide and Penn Radio. Now don't get me wrong, I love Penn Radio (I'm leader of the Goudeau Army East Asia Chapter) but I find myself, more and more, gravitating towards the Skeptic's Guide. It used to be if I was half way through a podcast of the Skeptic's Guide and I downloaded a new Penn Radio show, well, I'd stop listening to the Skeptic's Guide, listen to Penn Radio, and then go back to where I left off in the Skeptic's Guide.
More and more I find myself finishing a full episode of the Skeptic's Guide before I give the latest Penn Radio show my attention.
Both are great shows, but I have only one brain and one 20 minute walk to the subway station. Something has to take precedence.
What's your choice?
