General description

A non-hierarchical keyword categorization system is used on del.icio.us where users can tag each of their bookmarks with a number of freely chosen keywords (cf. folksonomy). A combined view of everyone's bookmarks with a given tag is available; for instance, the URL "http://del.icio.us/tag/wiki" displays all of the most recent links tagged "wiki" (more about navigating tags). Its collective nature makes it possible to view bookmarks added by similar-minded users. A hierarchy (in Greek hieros = sacred, arkho = rule) is a system of ranking and organizing things. ...
