We had a great "media archaeology" panel at Transmediale 2012 -- organized by Timothy Druckrey, with Inke Arns, Siegfried Zielinski, Wolfgang Ernst and me. Really good interventions, and the discussions that ensued were helpful for people, I am sure, in carving out the different approaches. Much of the emphases went to a Zielinski vs. Ernst debate, that was probably for theatrical reasons a bit overemphasized -- but still, there are significant differences too: Ernst kept on emphasizing the importance of the mathematical and non-semantic mobilized also as media archaeological method (hence not just a theme for analysis), and Zielinski was keen to defend his poetics of difference, deep times, and so forth.
