Re: Really, guys?
Hmm. Node.js presumably works just great on big data for quick development and testing, right up until you actually have real big data coming in.
I bit like how Twitter proved how great Ruby-on-Rails was, until it fell over and had to be re-written. Or how Facebook used PHP, but had to write their own spec PHP->native code compiler because they were going to run out of floorspace for servers otherwise.
