So you've taken the idea of progressive enhancement and reversed it? Zeldman would be rolling in his grave... if he were dead, anyway. I've always found it easier to go the other way: make a site that works on everything, then just add bells, whistles, and enhancements with Javascript as you feel compelled to do so. Doing it this way, I find places I was going to use pure JS where there was no real value-add to it.
