Just a quick thought. with the advances in e-readers what would a combination of video and books be like. By this I mean a martial arts video has visual advantages because you can see the technique, but it doesn't necessarily have the depth that a book would have in certain areas. With digital media, imagine a book that is several hundred pages of information, and when the author wants to emphasize something visually, instead of pictures, you tap on the screen and watch a video of the point, narrated by the author. Then you go back to the text. Any thoughts? Would this be worth it? Imagine the Donn Draeger books on martial arts, but with video of the arts he discusses or videos of specific technique differences or points.
