I respect the ambition, but doesn't it seem like a waste of time and money for a brand new startup to focus on the creation of a brand new language (+compiler +debugging facilities +documentation for new employees +libraries +...) before making the core product? I understand the argument that better languages = increased productivity. But designing a new language is a serious investment, and unless what they've made is so revolutionary that it completely changes the web development paradigm, it doesn't seem as if it would pay off.
