I have lost my voice and therefore we will not be having class tonight. Keep working on your D3 while I keep working to grade D2 (22 hours of video takes a while!) And in the meantime, consider leveraging the YOUTUBE STRATEGIES textbook for this course by registering with the author at http://www.21questionsaboutyoutube.com/. Watch his pitch on that site and then decide if it is worth your while. The videos are actually quite helpful!
