Little bit off topic but WTF, while awesome, isn't really a comedy podcast because it isn't funny. If you're looking for something like that check out Comedy Bang Bang or something.
Comedy is in the ear of the beholder. I have had far more meaningful laughs (whatever the heck that means) at WTF then at comedy bang bang. I would say download both of them, they are totally different things.
I dunno, it sticks pretty close to the style and tone of Maron's own stand-up, which like Louis's is deeply personal and raw and itself challenges what constitutes 'comedy' to some degree. I'd say it's funny in the same way Maron himself is funny.
