Glenn and I were interviewed a few weeks back by howsoftwareisbuilt.com. Glenn's blog mentions the different people that are interview on their site including Michael Tiemann, Jay Pipes, Matt Gibbs and Shawn Burke. 

The subject of this interview was about patterns & practices, how we develop software, and how we are different. We talked about our Customer-Connected Engineering strategy, how we deliver guidance and our contrib. communities.
