The DaVinci Hustle, Part 4: MarkDRoberts.com.
The series is, simply, masterful. I cannot recommend it highly enough if you want to be prepared to discuss the book/movie with believers, non-believers, or anyone in between.
I also think the series demonstrates the incredible potential that the blogosphere has made available to scholars/writers who know how to use their learning to help a broad audience understand a complex subject, and to do so with all the tools available to a talented blogger, especially links, diagrams, photos etc. This series should get a chapter in a book on the evolution of the blogosphere as a tool of serious, effective teaching.
