I Thought You Wanted To Get Your Message Out?

I get confused when I meet bloggers who have great content but don't want to take the exact same information and turn it into a podcast. 

I may like your blog, but I can't read it on the way to work. However, I could listen to it if it was a podcast.

People on YouTube have audio recorded. All they need to do is pull the video into a program like Audacity and export the audio. 

You already have great content, but not everybody loves videos and blogs. You should repurpose your content and make it easy for everyone to consume their content in any format.
