Computer mediated communication at the end of the 1990s reconfigures the communications standards making possible the emergence of a many-to-many communication model. Today, the web is different, it is based on a cooperative process. Hypertext is reconfigured and web-users may not only publicize information, but also represent and retrieve it through specific tools. Drawing from a master’s dissertation concluded in 2008, this paper argues that folksonomy is a new type of hypertext and analyses how hypertextual processes of representation and information retrieval in del.icio.us and Flickr can potencialize collective memory in the web.
