Word of the week (and meme currently entering the second wave) is rhizome (and it's partner rhizomic).
"We're tired of trees. We should stop believing in trees, roots, and radicles. They've made us suffer too much. All of arborescent culture is founded on them, from biology to linguistics": instead, it's the rhizome, the interconnectedness. That article, by the way, is part of Mus(e)ings on Deleuze & Guattari, a collection of short essays tramplings on a fundamental metaphor set that underlies everything. From strata in rhizomes to positive ontologies (the this-ness of the is-ness), every single one is worth more than just a read. (Thanks Mr Sweeney.)
