Leo has his own podcast network called twit.tv. He launched in in the Sprint of 2005 with his first show being his flagship show, This Week In Tech. It's a round table discussions of the weeks top tech stories, John Dvorka is there sometimes along with other former ZDTV personalities. The Tech Guy is also a pretty popular one. It's a live call in show similar to Call For Help, it's a syndicated weekend show and broadcast live all around the country and on XM, its recorded and put up a few days later on the website. Sarah Lane, Beck Worley and Martin Sargent are also in some podcasts on Leo's network. Patrick Norton makes cameos on Leo's podcasts every once in a while, but he used to have his own called Digital Life.TV. He and Jim Louderback also used to do a podcast called What's New Now which was real similar to ZDTVs Fresh Gear. Both Jim and Patrick do shows for Revision3 now.
I've been listening to his various podcasts on and off since Fall of 2005. This Week In Tech, The Tech Guy, Net@Nite, Security Now and Daily GizWiz are among my personal favorites. I haven't checked out some of the newer ones though. And there are some video podcasts too! If you have a smartphone, you can stream all the TWIT shows via the app, I know there's a twit.tv app in the Apple App Store and Android Market, not sure about Blackberry or WebOS.
