I wouldn't want to browse with anything but NoScript, CS Lite, RefControl, Adblock Plus and Ghostery. If your site doesn't work, too bad for you. I'm not the person who makes a living selling stuff on the interwebs.

There are useful applications of Javascript, but they are rare. You have to show me that it's useful to me, and I will then give you my CPU time. Not the other way round.
