+* Hack with Common Lisp.
+
+  While most of my Lisp-writing has been in Clojure, the majority of my
+  Lisp-learning has been in Common Lisp. Fanboys say there's nothing you can't
+  do with CL, and, while I don't have enough experience to confirm or deny
+  this, I always enjoy exploring the language. The Emacs/CL ecosystem is
+  amazing as well.
+
+  SLIME is indescribably good. 'Nuff said. As for the configuration, I set SBCL
+  as my preferred Lisp, and tell SLIME to look fancy.

+  Integrating Auto-Complete and SLIME is painless, thanks to the work of Steve
+  Purcell.
