I’m not a podcast junkie, but I do love NPR.  So most of the podcasts I’ve listened to are NPR podcasts of my favorite shows (This American Life takes the top spot).  I have also listened to some podcasts done by LISnews and I’ve enjoyed them.  I wasn’t overly impressed with any of the sites here.  Podscope, podcast alley, and get a podcast seemed okay, but I guess I liked podcast.com best because the search results I got seemed the most relevant to what I was actually looking for.  They also had good subject breakdowns which always makes me happy!  They had some great book oriented podcasts up and I enjoyed how they displayed content.  I get the New York Times book review RSS feed, but it might be nice to listen to some podcasts.   I also found some interviews with authors there that seemed intriguing.
