Hence, Soundbord. It's a pretty simple app. On the server it's a basic Sinatra app serving up a single html page. The front-end uses HTML 5 Boilerplate, and the jplayer jQuery plugin to actually play the audio. Jplayer is great because you don't have to know much about HTML audio to use it.
I downloaded all the shows manually and extracted clips with Audacity.
I'm open to requests for additional soundbites. If you have one, open an issue here, and pretty please add a timestamp and show number, so that I don't have to sift through hours of podcasts.
