Clojure!
I played around with common lisp a bit a some months ago, though I basically used none of the lisp specific features like macros.
After reading a few blog posts on functional programming and "the lisp way" I have decided to buy a book on Clojure. My end goal (for now) is to build a basic website with a backend.
Fulcro is huge and might be a lot if you're just starting to learn Clojure too. IMO Luminus is a pretty nice option that lets you start simple and add more complicated pieces as you require.
