I understand the critique being made, but this seems like a slightly outdated view of Haskell. There is quite a bit of software being written in Haskell these days. One project that got some press recently is a long existing project that recently went open source, Cryptol [0].
While lots of projects in Hasekll continue to be libraries written for Haskell, there are also lots of languages using Haskell for their implementation language. Browse the GitHub trending repositories listing for Haskell [1] for an idea of what is being done with it.
