I looked at Podcast Directory and I just didn't like the design (or lack) of the website. So yes, there was information but there were also a bunch of ads which blended right in with the rest of the page. Podcast Alley suited my aethetic much better. The search tool was easy to find, navigation was easy and there were some featured podcasts that were interesting. But I wish that the directories had short descriptions of the podcasts.
I was happy to find on the NPR directory, that the Whad Ya Know? Show -All the News that Isn't, which I grew up listening to every Saturday morning, podcasts its shows and has an audio archive of the past year's shows. Good ol' Wisconsin entertainment!
*The answer to the question "Whad ya know?" is "Not much. You?"
