I love the content of these podcasts. More power to you. It would be really helpful if you explained a bit more who you are. Are you history/politics professors? You need to do a proper intro to each episode explaining what the goal of the show is, and explaining each time what it is you are doing and who you are. You need to spell out names and explain references. For example I had not heard of Andreessen and was interested enough to search for him. I am a determined engaged listener though. I think it would be worth the effort to reach more people. By the way, the latest podcast, which has a great title and photo, starts mid sentence, did you realise? I search for B5 a lot and that's how I found this gem.
