I've been listening to a lot of podcasts all of a sudden, and the one I'm going to recommend most highly isn't one I'm affiliated with in any way. I haven't promoted my book on their show, or done an interview, or anything. But I did spend hour after hour listening to their back catologue today after listening to their "best of" feed on the CGS site. Unlike many comic book podcasts, these two guys, Matt and Jon (based in the U. K.), don't list a bunch of new releases, revel in obscure trivia, or even spend any time reviewing comics. Instead, they discuss the greatness of Rob Liefeld and his ability to draw lots of pouches, enthuse over anything Feedback-related, champion the return of the Green Lantern squirrel Ch'p, and look for hidden ninjas on every page of every comic book. If you like fun, and you hate not fun, check out their podcasts and listen along with me: Quiet! Panelologists at Work
EDITED TO ADD: Okay, I finally listened to ALL of their episodes, and it turns out that they do, in fact, promote my book in episode 22. They do a fake interview with "Timothy Callahan" that is quite brilliant.
