It could be fun but we'd need some sort of managing system so not only users with a particular bias get to hog the screen time every time and, of course, people who can be vocal about their opinions in a way that is both entertaining and informative.
There aren't a whole lot of people like that, especially considering that they'd need to live in the same vicinity and all the podcasts would likely be from the US, which also limits the appeal somewhat for many.
I did vote yes though, I could see this as a terrific idea if it was made to work somehow!
