Right now, nodejs shines anywhere you need websockets and I personally want to see the modern web move to websockets. It allows for much more cool interactions than the server being unable to get data to the client without the client either clicking on something or constantly polling. On a bb software, having the "this thread has unread posts" indicator update without a page reload would be great, and websockets make that easy.
