Just ran across this on the Apple/iTunes Store's Podcast front page:
"The Sporkful" podcast
http://itunes.apple.com/us/podcast/the-sporkful/id350709629
"Learn to eat more better" - mastication and rumination.
This latest episode has Jesse Thorn on it. I've heard him as the bailiff on Judge John Hodgman. I had an online training course and the trainer sounded exactly like Jesse Thorn and I told him that.
Have not perused it much yet.
