The Next Generation of Talk Radio...

Was it Andrew Wilkow that coined the phrase "The Next Generation of Talk Radio"? What exactly constitutes the "Next Generation"? It's obviously not an amazing speaking voice. No, no, don't get me wrong! I understand that a radio voice like Rush's or Beck's is a very rare thing and it's obvious that Hannity's rising ratings are in no part due to an amazing radio voice (he's very nasaly!). So...who else besides Wilkow is part of this "Next Generation"? Who are the "Next Generation" hosts of the same caliber of Rush and Beck?
