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.

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

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

”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
