M.C. Escher: House of Stairs, 1951

New technologies alter the structure of our interests : the things we think about .

They alter the character of our symbols : the things we think with .

Neil Postman, Technopoly , 1993

Ericsson Medialab Internet = computer network

WWW = document network www.cybergeography.org/atlas/

Adamic et al. (2003). A social network caught in the Web Web 2.0 = person network

Web 2.0 = “ participative Web ” = “architecture of participation”

Web 2.0 = buzzword: Tim O’Reilly 2004

Web 2.0 = “ user-added value”

Web 2.0 = create + connect + collaborate + share + remix + ..

blogs, RSS, wikis, tagging, folksonomies, etc.

Web 2.0 = social web / social software / participative media

Web 2.0 = Web “0.0” = Tim Berners-Lee’s original idea with WWW 1990

tools for easy collaboration and ressource sharing

web 2.0 = social software

”… supports, extends, or derives added value from human social behaviour …” (www.plasticbag.org/archives/2005/01/an_addendum_to_a_definition_of_social_software)
