It seems strange to me they would go on so long about podcasts and really only talk about public radio-ish podcasts. I've been listening to podcasts since the time when it was best described as an on-demand public radio feed. Public Radio has been riding the peaks and troughs of podcasting, but I wouldn't say they are leading any renaissance, real or imagined.

If there is a renaissance, it's being created by comedy podcasts. Let's mention:

Jordan Jesse Go!

WTF with Marc Maron

Comedy Bang Bang

You Made it Weird with Pete Holmes

The Nerdist

Doug Loves Movies

Harmontown

And I'm not a huge fan but you have to mention Adam Carolla and Kevin Smith here too.

These are the people who made podcasting more than just convenient radio.
