Summary of the idea: a web-service that makes it easy to plan an education program on any discipline and share it with the world. People may search for specific keyword, for example "Ruby On Rails", then they'll be handed a list of plans created by others. A plan is a document that describes what a person should learn (subjects, concepts, books, articles, other plans) in order to become a "novice", then a "mid-level" and finally a "senior" specialist. A plan by default is editable by others (with author's supervision) and others may, thus, contribute and rearrange it.
