The part about interviews vs. auditions is around the 49 minute mark. The entire podcast was fascinating. The topic of the podcast is his recent book about Gawker and Peter Thiel and a broader discussion about "conspiracies".
It was a really good podcast. One of my takeaways is that Holiday does a good job of not "taking sides" even though it is a seductive, socially compelling thing to do. I think that EconTalk and the book deserve their own HN thread.
