Social bookmarking is a new concept that has seen the light with the emergence of bookmarking services like the ones I cited below.Semantically speaking, ' social bookmarking' is made up of the the term " social " which is related to society and general interactions between people, and the verb " to bookmark " (used here as a gerund ending in ing) which has to do with recording and/or saving content for both later use and quick access. Weaving the semantic reference of the two words results in social bookmarking as we know it today : a collaborative and collective saving and sharing of web content.'
