As with all attempts at making big lists insiders don't really care about this one is perpetually out of date. Every time someone posts a message on Facebook it goes through an anti-spam system written in Haskell by way of their `Haxl` monad which automatically batches resource requests, "figures out" what it can fetch concurrently (not really, it's a feature of `Applicative` vs. `Monad`). People go on and on about how Haskell is niche, but I haven't made a job search in a long time where there weren't more results for Haskell than Erlang, for example. Among the rarer languages it's clearly one of the more popular ones. Yet, here we are, people talking about it as if it's somehow less used in industry than all of the other FP languages. OCaml is an interesting example. Usually people who haven't used either language outside of a few Sundays here and there will talk about how OCaml is more practical than Haskell and is the more obvious choice for industry... But on just indeed.com as an example it currently has 63 listings with the top ones being for developers in other languages. Haskell has 479 (again it's popular to search for Scala developers by saying they ought to know Haskell).
