Using Clojure actually isn't that hard. It is basically the same amount of difficulty as any other compiled language. You can basically take any text editor and do a standard 'write->compile->run'. However, most people that are familiar with Lisp, prefer a more interactive development environment that allows you to make changes to a running app. Probably the most powerful environment for doing this is SLIME in Emacs. As a result this is what is mentioned the most. I think this tends to scare people off.

I don't know why the Enclojure plugin for Netbeans isn't mentioned more. It provides an interactive development environment for Clojure in package that is much easier to digest for anyone who is familiar with an IDE.
