I strongly disagree that unpolished programs (done under time constraints or otherwise) signal that a language is more than something satisfying (academic) curiosity. I am a contributor to the Yesod web framework (so I know this example is a good one - there are certainly others). Yesod is robust software used in production right now. Feel free to point people to www.yesodweb.com as an example. We are doing traditional IO-heavy database oriented web development, but leveraging Haskell to make things better in ways not possible in other langauges.
