Is there much clojure in KC? The only company I know of so far is Cerner.

Sadly no… I live and work in the Bay Area most of the time now but still have a home in KC and come back often. Would love to see a bigger Clojure presence in KC. Only other Clojure dev I know of here is Jim Duey (…the guy who wrote Toccata, …Clojure dialect that compiles to C).
