I am a fan of the podcasts produced by Leo Laporte's TWiT network. His network produces about 16 shows a week. The best (from my point of view) are MacBreak Weekly and the original This Week in Twit (TWiT).
This week Leo launched his brand new show, This Week in Google. Hosting with him is Gina Trapani, andJeff Jarvis. I have listened to the first show and considering the impact Google now has on most peoples lives this is great way to hear some informed discussion on Google and where they might be heading.
