How to become better in 2008, how to audition well in your home studio , and where the real money is in voice acting are the topics of some excellent podcasts I've heard recently:

First, at Voices.com, one does not need to be a paying member for all the fabulous free podcasts to be found at Voiceover Experts. There's a new one from Rodney Saulsberry, and another from Marc Cashman about how to audition in your home studio.

There's another podcast by Bettye Zoller Seitz that's offered by  content-loaded site, Voiceover Extra.

Lots of great information abounding!
