⟩ What major web sites do the best job of optimization?
Yahoo.com has the most highly optimized home page I have seen. They use URL abbreviation to save nearly 30% off their home page HTML. View source to see what I mean. But even Yahoo has bloated up, they have nearly 300 links on their front page. WebReference.com of course :) I like most anything from Zeldman and company, very clean and CSS-based. Though there's always room for improvement.
