Because in all likelihood, the jobs most of us will be interviewing for will never require us to touch Haskell or ML. I haven't worked with it, but I've worked with Lisp/Scheme/PROLOG and others. I'm always down for learning something new, but I doubt many people here get paid to write Haskell on a regular basis. Or maybe I'm wrong?
