It's mildly amusing that this page itself doesn't render without JavaScript enabled.
JavaScript is killing the static Web — and IMHO that's a terrible thing. In part, I imagine Google like JavaScript pages because it's a barrier to the entry of another search competitor.
I think the good people at Scrapy [1] have done a great job in keeping pace with making open-source crawler components that handle javascript. It is called Splash [2], and I use it for rendering out screenshots.
