Hi, Ulla. Through Trebor Scholz in the IDC mailing-list I've found a presentation made by the futurulogist Jamais Cascio which is available here (http://www.worldchanging.com/archives/002651.html; and here http://www.itconversations.com/shows/detail375.html). In that presentation, Cascio explains the meaning of the participatory panopticon, a term he has coined to refer to the concept of widespread and ubiquituous "sousveillance" where every bit of information about every citizen is being permanently recorded and made accessible to everyone else. It might sound like the regular talk of a pundit, but he delves deep into this scenario and males plausible assumptions. It might be of some interest. i also recommend checking out what Nathan Lovejoy has been writing in Swarming Media (http://www.swarmingmedia.com/) about the redefinition of privacy and control in the age of Web 2.0 and pervasive social networks, He analyses the dissolution of fixed and stable identities by way of tags, folksonomies and other types of social classification seen in MySpace and Del.ici.ous through the lens of Foucault and Negri's writings.
