We do put a lot of time and effort into our podcast, though. We're avid fans of Radiolab. The first episode was just rambling - but it was the 5th take of rambling, at least. Our 4th episode was a thoroughly researched one where I introduced my co-host to some basic statistics I had to learn as part of the research (null hypothesis, precision/recall, ...) that Microsoft did after Vista to figure out why it went wrong. The 5th episode was about Linus Torvalds' book Just For Fun, where I read the book, annotated it heavily, found an interesting narrative and perspective, and read from the book and tied it into one of my favorite moments of the Breaking Bad insider podcast. Our upcoming 6th episode is going to be about the early Stack Overflow podcast episodes, where Joel and Jeff discuss in detail how they're going to make a successful QA site that at the time absolutely was not guaranteed to be successful. (Yeah, I know, very meta :D)
Maybe podcasts are like tenure at universities... 95% is wasted, but the other 5% is so good that it's worth it anyway? Hopefully we can contribute to the good parts of the podcasting sphere.
