Tags and tag navigation could offer a new and better way of finding and organising information on Web sites, Help files, procedure documents and Intranets. del.icio.us, flickr, technorati are examples of sites that use tags. These sites allow more than one person to tag a particular entry, and create multiple navigation routes, although it is possible to build a site where all the tags are from the author.
Enabling the users to decide and develop the navigation routes in this way could lead to consensus or to anarchy. We think it could work well.
