Not looking at youtube. But if that something people want I can look into adding that as well. Currently there are crawled on itunes, spotify and soundcloud.
Might be interesting to do; lots of stuff on YouTube (even though it has video) make for wonderful podcasts. Even if you project out the video content, they're still worth listening to. Not sure if they make it easy to distinguish between videos where the video part matters.
It looks like you don't have 'The Joe Rogan Experience' podcast either - 0 results for 'Rogan'. It's one of the most listened podcasts in the world so I think there's something wrong with your crawling.
