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

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 …”

small-world semantic network

All shortest paths between the terms volcano and ache in a semantic network formed by free word associations

Web 2.0 = person network

social graph ”global mapping of everybody and how they are related”

(Fitzpatrick & Recordon 2007: Thoughts on the social graph)

Web 2.0 = person network = social graph

Google Social Graph API API = application programming interface

coding publicly declared web connections XFN = XHTML Friends Network

FOAF = ‘Friend of a Friend’ project

http://code.google.com/apis/socialgraph/docs/

”social network portability”

Google OpenSocial API API = application programming interface

API for “social applications across multiple websites” ”many sites, one API”

e.g. Friendster, LinkedIn, MySpace, Oracle, Orkut, Plaxo soon also Facebook applications
