Well, This American Life and Serial are done by the same people, so that's not surprising. The "StartUp guy" was a producer for TAL for many years so that's where that connection comes from.
Also Blumberg's input on Planet Money quickly descended into the worst kind of sycophancy. naked capitalism did a very good job of calling him out on it. It's a shame because some of the early shows (eg giant pool of money) were very good.
I'm interested. Could you point me to a link to where naked capitalism calls out Blumberg? I hadn't actually heard of that site (show?) before and an initial Google isn't bringing me anything. Thanks.
Planet Money, which was Blumberg's main podcast for the last few years, is also a spinoff of TAL (created after The Giant Pool of Money episode[1]) and produced in partnership with them.
