The author Fredrik Österblom got in contact and kindly sent me the article in question. It’s in Paletten issue 3: 2012 #289; p.29 (Graham also emailed me about this).
UPDATED: (My translation was awful, so addressing the comments below and from Fredrick’s email, I’ve put their translations in) ;
“In recent years, an object-oriented movement extends far beyond the philosophical discipline. Graham Harman’s philosophy has “gjort sig märklig” (“made itself visible”) in areas such as Art (Robert Jackson), ecology (Timothy Morton), literature (Eileen Joy) and political theory (Levi Bryant). In comparison to the speculative realism “spretighet” (diverseness) the OOO movement uniform is tied around a common issue. Most of the key members are active bloggers and theories have in a significant part emerged and spread online.”
Thats very kind of Fredrik to mention me in the same analogical vein as Tim, Levi and Eileen (Bogost should definitely be added, perhaps under media/videogames) – I don’t, however, consider myself to be anywhere near the prestigious level of anyone else in this OOO crowd; as a PhD student I have not earned my academic chops to get to their level, but maybe some day. That and the fact that all of us have talked about art and OOO in some way or another.
He’s right in one way thought. We all are tied by common issues specific to the challenge that Graham has opened up – issues which last a lifetime to think over.
