that quote reminds me of one of the good things about Clojure — that it can bridge to an organization’s existing Java libraries/frameworks


Holy crap, 50 engineers!! That seems like a lot.


But consider the number of users to engineers as a ratio. Pretty insane. Personally, I think it’s kind of funny FB moved away from Erlang in their system, and then brought it in through the largest acquisition in history


(Though the reason FB moved away, as well as the reason WhatsApp uses Erlang both seem pretty reasonable)


Just 50 engineers for ~1B users is awesome.


Compared to e.g. Google
