Video Knols - Big Scope
Video blogging, sometimes shortened to vlogging or vidding or vidblogging is a form of blogging for which the medium is video and is a form of Internet television. Entries often combine embedded video or a video link with supporting text, images, and other metadata. (Wikipedia http://en.wikipedia.org/wiki/Video_blogging ).
The definition can be slightly modified to include blogposts with the main content as video, as video blogs. From there it can be extended to knols. Video knols are knols where the main focused content is a video. While videos can be prepared by the authors themselves, there is lot of good content on Youtube awaiting distribution. So knol authors can select useful videos and can highlight them through their knols, My idea of Knol books is an useful channel for collecting videos belonging to a subject into an online book. I am trying to create some video knol books.
