I have grown to love NPR's all tech considered podcast.http://www.npr.org/templates/story/story.php?storyId=97097438.
I am trying to build a regular feed of interesting pod casts and tech shows(with a tech flavor) .Some of them that come to my mind. 1. BBC's click http://news.bbc.co.uk/2/hi/programmes/click_online/default.stm 2. Tech Podcast from PRI:http://www.theworld.org/technology-podcast/
Feel free to add to the list !
