online tutorials

So in wanting to expand my venture, I am considering posting up online tutorials on youtube. I want to make videos of me demonstrating some of the moves we've gone over in class. I hope that eventually I may even make a short dvd that I can hand out or even eventually even sell. My question to you is... would you all find it helpful? I figured it's another tool to help you all on your way. I would appreciate the feedback either through here or via email. Your thoughts count. Thank you.
