Haskell over the years

How has the usage of Haskell changed since 2011? back then it was good for writing toy programs like project euler solutions and underfeatured windows managers. Now I took a look and it seems to be used for toy programs like underfeatured http servers.

where is the haskell/lisp/rust/ocaml software revolution with thousands of projects and industry support?
