Ask HN: Why isn't Scala as popular on the HN front page as Haskell or Go?

I thought it had all the components to be popular among hackers and web developers, did it simply pass its hype curve? or is there a specific reason why it's less popular among HN readers than let's say Haskell / Go? I love reading articles about Haskell and Go, and think they are wonderful languages, but is there something specific about Scala that makes it less popular among HN readers?
