I think it's great that there more end-to-end JS options emerging. JS is in many ways just as sane and capable to write server-side code as Python, Ruby, or PHP. It is obviously capable client side because it's basically the language that powers Adobe AIR apps. Funny enough, Javascript is about the only common language that every major tech company can get behind.
