A month or so ago Tim Bourquin of TNC Media asked me if I would be willing to be on a panel during Podcast Expo. He asked me to be on the Panel titled "Monetize with Ads and Sponsorship: Use An Advertising Service or Sell Your Own?" being that I have sold my own, and actually run a advertising service for over 500 podcasters this was a good fit. The panel is made up of some other firms that represent podcasters and should be a lively discussion as all of our models are a little different.
