The 2012 'State of Clojure' survey is open

Prior years' "State of Clojure" surveys have been such a success and yielded such valuable data about the Clojure community that I had no choice but to do it all again! The 2012 State of Clojure survey opened this morning, and will remain open until Thursday, July 26th: http://cemerick.com/201
