The self-selection of people I follow on Twitter, the meetups and conferences I attend, the choice of companies and colleagues I have worked with, etc, probably just reinforce my blinkered echo chamber. This is probably true for many Haskell, Rubyist, Go people and others as well.
By heart, I would have guessed 20% Scala usage, but in my head, I do know of the floods of javascript misuse across the world, the legions of java developers in every country and location, having been one myself once. And I guess my current location of London which I feel use Scala more than most places and mixing a lot with startups does affect my expectations of what everyone else use elsewhere.
