I was about to say that it's quite smooth for me on Safari - then I searched for something as per your suggestion and the whole page was vertically offset and effectively broken... oh dear. Edit: The scroll hijacking makes more sense in the context of the home page, which actually uses it to reasonable effect (not endorsing the technique, but the home page is attractive at least). I think the mistake was leaving it on for heavy content pages like the one linked where it adds very little but breaks other basic behaviour.
