There aren't a lot of consumer facing companies using Haskell. Scrive is one, but I can't find blogs.
Galois makes "highly reliable" software stuff for hardware manufactures and crypto clients.
Edward Kmett is writing/using a Haskell variant for use at the bank where he works.

Elm is a FRP/DHTML webapp-building language Haskell variant whose compiler is a Haskell program. Check out Prezi and Evan's blogs
Prezi.com recent hired its author Evan Czaplicki
Yesod (Michael Snoyman) is a full-festured webapp stack. Michael blogs its features.
Ultimately, you don't see large teams using Haskell, and there isn't full integration with all the popular consumer web infrastructure. So instead you have a bunch of small niche products, and the language used to teach mathematical concepts in blogs like Dan Piponi's
But even there the goal is not about adopting Haskell in the large, but using rather using Haskell to create a DSL for end users/employees internally in FB to easily create search/spam filter behaviors.
