These days a small language called Pure has my attention (purelang.bitbucket.org) - it has many of the features of Haskell I like, but is a dynamically typed language that makes use of an interesting functional paradigm (term rewriting calculus!), and is much easier to use than Haskell. It also has a great shell and C/C++ interface (and Emacs and Texmacs integration).

And I always like seeing these kinds of polls because people's 'favourites' depend alot on what they do with the language - Java and C++ are great for writing large apps, systems, etc..., while dynamic languages have much different use cases.
