I know that in the past several companies like Viaweb and Reddit have used Lisp for their production services. After reading Hackers & Painters I've been motivated to deepen my Lisp knowledge, so I'm wondering, who's using Lisp in their production systems today?<p>I know HN does, but is there any other known website currently using it?
You can also look for companies doing Clojure a Lisp on JVM. You can view a list here <a href="http://dev.clojure.org/display/community/Clojure+Success+Stories" rel="nofollow">http://dev.clojure.org/display/community/Clojure+Success+Sto...</a>
Here is a list of succesful companies using Allegro Common Lisp:<p><a href="http://www.franz.com/success/" rel="nofollow">http://www.franz.com/success/</a><p>[Note: I don't know if it's up-to-date and how significant is actually common lisp in those companies codebases.]<p>Also as a side note, Reddit is no longer using lisp, they are using python.
