“Social navigation has been proposed as a means to help users cope with large information spaces. Through making other users actions visible we can take advantage of their work to find our way around and to solve problems. By information space, we mean anything from the interface to a normal application to large hypermedia spaces such as the World Wide Web or virtual reality environments. Users actions can be made visible in various ways: through direct social navigation (talking to or seeing individual users act), indirect social navigation (seeing the aggregated user behavior as in recommender system advice), or readwear (seeing how an object has been used by other users through its texture).”
