The Clue Unit Podcast.

Here is a great podcast involving discussion of the relationship of social networking and businesses. The podcasts are organized around a theme each month. Last month it was business transparency: giving a human face to companies and building customer relationships in that way. This month it is businesses that rely on communities such as Threadless and JPG magazine. Another topic theme was Co-creation: products developed primary by people in communities, not employees. This apparently was very successfully done by Lego. Fascinating concepts along the line of the "Cluetrain Manifesto."
