Hey! I think this is a great idea. In fact, my gamedev partner and I did a sort of postmortem/review/discussion in podcast form. This is our first ever podcast, but I think it was fairly interesting, and I tried to make sure the audio quality was half decent. Let me know if you find it helpful/interesting or if you have any other feedback to share.
