there is no much sense indeed to use node right now as a complete backend solution. There are much better ways to push out html and do db queries ;) This being said, there are lots of use cases where node shines. In short - anything related to push or massive number of connections. So if you are building a chat server it doesn't make much sense to write it in rails or django as your server will die as soon as it gets even slightly popular; and fixing it at that stage will not be tuning this or that. you will have to rewrite it. probably in node.js ;)
