Batchelor seems to alternate between having one of his financial cohosts fill in on Saturday, or he does recorded (but fresh) interviews, mostly with authors of history books.
Unlike other shows where the host says nothing and is just vamping until the next break, every minute of his show is non-stop content.
Part of the answer of how he is able to generate 24+ hours a week of high density content is he knows a lot. There is no substitute for that. If he has a guest (like this week) who is discussing the failed attack by the American Navy in 1779 in Maine, he doesn't need to read up on it. He's been there and knows the history of the battle.
John is using a Macintosh for his editing and production. His guests are generally on Skype. He uses a Kindle to read the many books that discusses on the show. His shows are available on every major podcast outlet for free without commercials.
He also seems to have a lot of contact with people from the Hoover Institute - they probably provide some of the material he uses.
Back in 2008 during the collapse of Bear Stearns and then Lehman, John was right their discussing CDOs and Credit Default Swaps, the unraveling of GM and Chrysler. Not reading headlines from Drudge, but talking to people who knew what it meant and what was likely to happen next - and having a probing conversation, not paraphrasing a preproducted segment written by someone else.
Keep it quiet. The only thing Citadel could do for this show is to screw it up by bringing in consultants. I just wish it was on a few hours earlier so more people would be aware it is there.
