Speaking as someone who has dabbled in both Haskell and Clojure (emphasis "dabbled"), I'd have to currently recommend Clojure over Haskell, for a couple reasons: * The Clojure community has a strong focus on web stuff, while the Haskell community has (to date) been primarily concerned with more math-centric fields. * Haskell's web stack is still very much a work-in-progress. It severely lacks when it comes to documentation of even "simple" stuff necessary for the web, like shuffling data into a database. Unless you're looking for a type signature. The Haskell community loves to provide documentation in the form of type signatures. * Learning curve. While both are functional languages, it was my experience that Clojure's emphasis on simplicity and ease-of-use made it very easy to pick up and start tackling real things. There is some ramp up time if you're getting used to the tools, such as Emacs or the Java ecosystem, but you don't have to worry about things like monads slowing you down. * It's a LISP! LISP is cool.
