Franz-- Interesting project...I would add to Andrew's excellent list my own paper, particularly if you are interested in noting interactions among multiple social groups: Kilker, J. (2002). Social and technical interoperability, the construction of users, and 'arrested closure': A case study of networked electronic mail development. Iterations 1(1) (Charles Babbage Institute). http://www.cbi.umn.edu/iterations/kilker.html Abstract: Behind the e-mail's success lies a history of extended social interactions among ARPANET developers, programmers, and users from relatively heterogeneous backgrounds. An analysis of social identifications present in online discussions about e-mail development found that inter-organizational computer networking allowed an increasingly wide variety of programmers and users to interact; assumptions about users to be openly stated and challenged; and the prototyping and testing of new technologies in heterogeneous social and technical contexts. Technical interoperation and its social analogue, social collaboration, became key challenges in the development of networked e-mail and led to "arrested closure" in the form of flexible standards. --Julian J.
