We do them every time Keith and I have both mutual availability and something interesting to say. Sadly, as of late we've both been very busy. Hopefully mid-January. (If you have a burning urge to hear my voice, I'm a guest on other folks' podcasts more frequently than on my own. http://productpeople.tv/ has a recent interview about my business story and Amy Hoy should be publishing a long interview about infoproducts (like our courses), multi-product businesses, and consulting sometime in the next two weeks or so.)
Part 1 has his complete back-story: everything from how he learned to program with graph paper to how he built his first product business with $60.
