Not sure, but how big are the pools of Haskell-devs over at Galois, FPComplete, HKIO, Facebook, Tsuru Capital, Type Safe, ...? Probably under 100, but not sure

Not sure, but how big are the pools of Haskell-devs over at Galois, FPComplete, HKIO, Facebook, Tsuru Capital, Type Safe, ...? Probably under 100, but not sure though. I dont think this learning curve/hiring thing makes sense. Haskell can help attract smart dev, it makes refactoring so easy increased learning curve is off set. I'd say it's harder to outsource, and there may not be as many libraries. Compare to Ruby/Rails for web, or Python for ML, and you have to write more by yourself in Haskell.
