"are not self sustaining; they rely on hundreds of thousands people, machines, and codes to make the network. They are collective, that is their length and durability are woven between the capacities and practices of actants-in-relation. They are hybrid, combining people and devices and other living things in intricate and fallible ways in the performance of social practices. They are situated, inhabiting numerous nodes and sites in particular places and involving their own particular frictions (cultural and environmental) to network activity. And, finally, they are partial even as they are global, embracing surfaces without covering them, however long their reach" 26
