It's disappointing to see Scala diehards coming here and downvoting anything that isn't glowing sycophantic love of scala. That's not leaving a good impression to the neutral crowd at all.
You see the way they squirm? They can't accept any criticism and therefore refuse improvement. They just want to sit there and be hobbyists. Not on my investors' dime!
Isn't it more likely that some comments are downvoted by the general HN population, because they don't add anything useful to the debate?
By the way, I just clicked your link, and I can't really how they support the point you are trying to make...
