Not really relevant to the article itself, but I've always been surprised how much attention Facebook's Haskell usage gets compared to Facebook's Ocaml usage.

From interning at Facebook, the only project that I'm aware of that uses Haskell is Sigma. On the other hand, numerous projects use Ocaml: Infer, HHVM, Flow, ReasonML, Pfff, etc.

However, it's Haskell that gets all the attention on Hacker News.

I’ve seen them recruit for a second Haskell team, I believe doing internal analytics or machine learning.
