Perhaps you are talking about the transformation of the passing of knowledge from a vertical model (the father tells the son, the professor instructs the student); to a horizontal model (the the brother tells the sister, one worker shows another worker.) Horizontal is the newly expanding model, and interactive internet video is one of the newest important tools in this transition from vertial to horizontal passing of knowledge. We are using the horizontal model and interactive internet video to train a new generation of tradespeople restoring historic buildings and preserving their cultural value here in the USA. In the tool box interactive internet video Qik.com is one of the newest tools. We have also been using these tools: Kyte.tv, FlashMeeting. --John Leeke, Portland, Maine, USA www.HistoricHomeWorks.com JohnLeeke@HistoricHomeWorks.com
