Super User says it works best with JavaScript enabled. I would change that message to:
Super User does not work without JavaScript.
Personally I dislike the JS layer, and switched it off, but then the post buttons no longer work. Can someone make the buttons work as normal HTML post buttons when JavaScript is turned off? That way the red message is more correct.
Strangely enough, the Post New Question button DOES work. Although you have to jump through a very complicated Human Being check. But the Answer buttons don't work.
