You're not missing much by not knowing who he is. This is one of the people the powers that be on the left are trying to astroturf hard as part of their effort to build a podcast/youtube coalition to counter the right leaning, Rogan manoshpere. None of that would have happened if not for the success of one his colleagues, Stavros Halkias or "Stavvy", who despite being a fat, slimey, scumbagish Greek guy on the surface -- actually is too funny and too honorable to sell out to this type of faggotry.
Listen to this if you haven't already. It may not play well to anyone over 40, but him riffing with Theo somehow works very well.
The podcast Stavvy did with Adam Friedland and Nick Mullen was called "Cum Town" and was quietly pretty successful.
I think it's best if we just all ignore Friedland. Guy gives me the douche chills.
