Who are the most inspiring communicators of math for a general audience? I have a podcast series (http://wildaboutmath.com/category/podcast/ and on Itunes https://itunes.apple.com/us/podcast/sol-ledermans-podcast/id588254197) where I interview people who have a passion for math and who have inspired others to take an interest in the subject. 
I've interviewed Alfred Posamentier, Keith Devlin, Ed Burger, James Tanton, and other math popularizers I know. I'm trying to get an interview set up with Ian Stewart and I'll see if I can do interviews with Steven Strogatz and Cliff Pickover in 2013.
Who do you know, famous or not, who I should try to get for my series? These people don't need to be authors. They can be game designers, teachers, toy makers, bloggers or anyone who has made a big contribution to helping kids or adults enjoy math more.

I recommend Art Benjamin.  He's a dynamic speaker, has given lots of math talks to general audiences (mostly on tricks for doing quick mental math calculations, I think), and is an expert on combinatorial proof techniques (e.g. he's coauthor of Proofs That Really Count).  Benjamin is a math professor at Harvey Mudd College.
