The “digital turning-point” triggered a partial but significant reconfiguration of sociability patterns and contributed to new ways of “doing things” collectively that have generally tended to move away from the model of communities shaped by a common sense of destiny, identity or belonging. The extension of the sphere of doing to technological fields is assumed here to bring a “chain of equivalences” into being, which links up fragments of involvement and subjectivity that do not necessarily require any prior agreement in order to function, except as regards the action aimed at. In other words, the increasing hold of information and communication technologies appears to be producing a more pragmatic and opportunistic tendency in collective action.
