When the edited volume Site Matters was first published in 2005, it was at a time when the meaning of the word site had just passed what we in hindsight may describe as the real/virtual tipping point. Having fulfilled its duty as a progressivist signpost in the zoning of the modern cityscape, the word was already back then fully registered as a basic staple of the network technology and the World Wide Web. If the word used to have certain concrete environmental referentials, according to the editors it had become increasingly ‘disassociated from the considerations of physical conditions’ (Burns &amp, Kahn 2005: ix) reflected in increasingly lofty and speculative, computer-aided urban design proposals, furthermore often projecting settings meant to be mediated rather than experienced ‘live’. Over less than a decade, the morphological and experiential variety previously implied in the word site—building sites, campsites, landfill sites, landing sites, nesting sites, picnic sites, or archeological sites, just to mention a few—had merged to form a generic, informational and communicative web-site, a mere placeholder for a mesh of interlinked, stacked and exchangeable content. When the editors of Site Matters, Andrea Kahn and Carol J. Burns, now return to the topic in a significantly revised second edition, the ‘mattering’ of site is of a totally different magnitude. While their initial holding on to site might have been motivated by its material and analog qualities, the rationale behind their updated attempt to gather site insights and know-how is much more existential in kind.
