There's two definitions of responsive, both of which are used in this thread.

1. It responds to your actions. Click stuff and it does that and does it quickly.

2. It gives you a different response based on which device you are using. You log on with a mobile device, it gives you a screen suited to mobile.

It doesn't do the latter. I'm on a phone. It might resize screens on a desktop, but doesn't do it for a phone.
