And what is "the community"?
Haskell indeed has less penetration than something more popular like JavaScript.
But the Haskell language is not easy to use if you're a script-kiddy. Most "easy" languages can have some form of copy-paste reuse, and a lot of "the community", it would seem, just append together useful snippets to get their programs done (and whether they have a deep understanding or not is not needed).
This isn't true for Haskell. It's actually quite hard to just "copy/paste" Haskell without out knowing the underlying concepts. I wager that the reason there seems to be less.of a community in Haskell is due to this property.
