I can&#x27;t believe an article about Lisp left out QuickLisp.  It&#x27;s the most popular Common Lisp package manager and has over 1200 open source libraries in it, and most of them are written in Common Lisp, or are bindings to native C&#x2F;C++ libraries.  Using libraries written in the same language you&#x27;re using has a lot of advantages.  Using Java libraries from a Lisp seems clunky.<p>Also, judging solely by the number of available packages is not a good measurement.  Browse through NPM, and it&#x27;s pretty obvious there are a LOT of duplicates, and that people have published libraries for the silliest little things.  Search for &quot;PNG&quot;, for example, and in the first page of results there are two different png diff libraries, a few libraries for determining if a buffer contains a PNG byte-stream, multiple stream and un-stream libraries, etc.  That&#x27;s all done with a single library in CL.<p>And finally, I don&#x27;t think Clojure is that great.  It&#x27;s better than Java, and it&#x27;s what I&#x27;d use if I had a lot of legacy Java code to work with, but it wouldn&#x27;t be my first choice for a new project written in Lisp.  I would hazard a guess that it&#x27;s popular because it&#x27;s less clunky than Java, without the over the top type system of Scala.
