Another question : How do you handle haters who claim Node is not really ready for production? Yeah, I have given many examples of sites using it ..PayPal, LinkedIn etc etc.. But I need a solid one liner! :D
I don't tend to argue technology, if someone has hired me, they've hired my experience, and I don't intend to discuss my technical choices with the client.
But if you want a one liner: "PayPal use it in production. They get a lot of traffic. And they're a complicated app. How do we compare?"
