Hi Christina,
Could you clarify your ideas on the "commodifation of discourse"? I'm unclear as to how and where this is occurring. Is it the concentration of discourse within the university/conference system? MIT Press? Siggraph? The abstraction of "place" into decentered space and time?... (but that's a more generic quality of Modernity isn't it?) There are certainly approaches to using electronic and computationally-based media that suggest the possibility of a reconstruction of space and time into a meaningful articulation of place. It's not the global network, or the telematic embrace, but perhaps new approaches to performance and presentation that allow the artwork to respond more directly to its place.
I wonder also if there's a critique per se here of the notion of interactivity itself? It seems to have been effectively appropriated by the world of management science and is couched more in terms of control, efficiency and ease-of-use for the "user". Artists are not users, but rather makers.... what is the nature of the things made? Use-value?... or something else?
Kenneth.
