Keenjar lets you organize online videos into courses (Stacks), making you independent from one single teacher.
Traditional education is based on knowledge scarcity. This model clearly separates people with knowledge and those without. However, on the web, knowledge is abundant and scattered all around, so there is in no one who knows everything about one given subject. Keenjar is a place where people can organize educational videos into Stacks, based on their subjects. Stacks give an easy access to many different videos and bring people together. Any member can add videos to Stacks, so they always remain relevant and up to date.
