WatchKnow is the new one-stop site for education-related videos created by Larry Sanger, a co-founder of Wikipedia. The site's slogan tells the story: “Videos for kids to learn from. Organized.” WatchKnow serves as a resource collection point -- an information database that makes it easy to search for and sort through videos that are tagged by topic and subtopic and have short descriptions and user ratings. Like Wikipedia, the project's success will depend in part on contributions of time from volunteers. But there's already plenty of content to search (12,000 videos) by topics (2,000) and age groups (3-18). Teachers were heavily involved in the initial selection of videos and the development of safety protocols.
