I don't think it's unreasonable to respond to a very poor quality blog post bashing Scala since it received very widespread publicity. The interesting story behind the story is the extreme enthusiasm with which Scala bashing posts are upvoted on various forums. It's highly unlikely that the majority of those voting have actually used Scala.
