title: Why Clojure over other JVM Lisps: Kawa, Armed Bear or SISC?
body: <p>The JVM already had three Lisps before Clojure arrived on the scene: <a href="http://www.gnu.org/software/kawa/" rel="noreferrer">Kawa</a>, <a href="http://common-lisp.net/project/armedbear/" rel="noreferrer">Armed Bear</a> and <a href="http://sisc-scheme.org/" rel="noreferrer">SISC</a>.</p>
  
  <p>What gap does <a href="http://clojure.org/" rel="noreferrer">Clojure</a> fill that was left by those Lisps?</p>
