I guess it is just a matter of taste. Clojure is the reason I have been writing software and it helped me to achieve things that would be very difficult without. It just has the right set of tools for a guy like me with systems engineering background. I find it much more understandable to use map + reduce than for loops, async instead of fork + threading code. The out of the box performance of JVM is also one reason I keep using Clojure.

Could you elaborate on this? Personally, I like the idea of Haskell about as much as I like the idea of Clojure, but Haskell has never quite clicked for me.

I don't think it's necessarily readability holding me back from Haskell, but I do find Clojure to be highly readable which really helped me get up to speed with it quickly. I'm curious what you find more readable about Haskell.

If you spend enough time in Clojure, it becomes quite readable. With threading macros and the like, there's no real reason you need many more parens that a language like Python.
