I'll just chime in on this from my perspective and say that video is a killer way to get rankings for many keywords. Youtube videos are tremendous for this. (Maybe I'll cover this later on in the course. Let me know if you're interested.)
P.S. It doesn't take any "video" skill to make a great traffic-generating video!
I didn't take video to serious until I started getting calls from a video that was put up on Youtube.
During a music conference I was in the expo area and grabbed the mic from my camera crew and started speaking to the audience (the camera). My videographer uploaded the video to Youtube. While being video taped I dared people to call me and let them know that it was my direct phone number. People started calling.
One of the people turned into a client that I now consult. Once the money cleared in my Paypal Account I stepped up my video marketing campaign.
After not wanting to wait for my videographer to edit my videos I learned how to do it myself. Chris you are right on time about using video and Youtube. It's amazing though how many people don't use it.
