Peter Thiel has never been classified as IDW member, but Ruben is considered a prime member, for his many Long Format Discussion using podcast, YouTube video platforms.
Joe Rogan's discussion with Elon Musk, recently was disappointing. This one with Thiel is fascinating.
My own criteria for using this IDW category, is the podcast video aspect. Therefore if I posted Victor Davis Hanson, I would put it here.
For me Scott Adams playbacks go here, too.
Hopefully Mark Levin will make his long format discussions available without cost. I think he is "on to" the popularity of the format.
