Great article! I program Rails by day, but lately have been working with the haskell Yesod framework: http://docs.yesodweb.com/book/basics http://docs.yesodweb.com/book/basics. It even has type-safe urls. I would disagree that lack of popularity of language is not a technical problem- it is because there is less community code available.
