Haskell is like the nerdy cousin of the ML family. Everyone knows he's smart, but no one would think to ask him to fix the kitchen sink or install the new dishwasher.

Seriously, Haskell is massively impressive, both as a research language and as an implementation. But it does not shed that certain research attitude. Every known problem seems to be boring. "Oh you want a proxying http server? No problem, this is just the inversion of the endofoo over the category of abstract Monobars!". Sometimes I get the feeling that no one focuses on shipping actual software with Haskell.

Facebook uses Haskell in a critical portion of their user-content publishing pipeline.

With just a modicum of effort you can easily disprove this feeling.
