Only begun learning it over the past few months, and only in my spare time, not commercially.
OO languages (C++, C#, Java, in that order) for the vast majority of my career (10 yrs).
So far (with little experience), I'm impressed by the simplicity of the basic primitives (ADTs, typeclasses, function eval) and how much abstraction you can achieve on top of that, in such an elegant fashion.
Been working in OO languages for years, but would really like to learn a/some FP languages. Never quite found the time, so I figured recently it was about time I found the time, and have been spending a bit of time recently with Haskell.
