Saying anything anti-rails or anti-apple on HN would be blasphemy methinks. I think the issue with node is it has a little bit of promise for a small number of applications, but there's a lot of falsehoods that are propagated around node. The whole "non-blocking means that it scales to infinity and beyond" and other stuff like that are things that need to be reigned in. Scalability is a lot more than just saying "well, throw nodejs at it and you're done."
