(1) Haskell, because I like functional programming, and this language seems very promising (I first looked at it 10 years ago, but I gave up because the implementations seemed immature. I took another look recently, and I'm amazed by how much it's progressed since then). I especially like the way that laziness and purity enable a concise, stream-processing paradigm through the use of maps, folds, and various combinators.
