You can download the podcast of my interview on the Steve Brown Etc. show this weekend. I had never heard of Steve Brown before the interview, but he was easily the funniest radio talk show host I've ever spoken with. If for no other reason, listen to the interview for the segment on the "definitions" of introversion and extroversion that he gives.
This link will take you to his website, where you can listen to it or download it:
