Makes me a bit sad, I built some very detailed and rich products on YUI. It was, at the time, the most well documented and comprehensively supported (for browsers such as IE6)framework around, and it had a complete set of widgets for every task. It was one of the few completely free JS frameworks I could show to enterprise and professional customers and not be embarrassed about. Unfortunately YUI3.x was a complete derailment for me. They tried to match the expressiveness of jQuery (which they only half achieved), but along the way the documentation got much worse, and half the widgets I was relying on disappeared and never got migrated to 3.x (with the excuse that you could run legacy 2.x alongside 3.x - do not want!)). I invested a lot of time, sweat and tears into this library and ultimately it turned out to be a big negative as my resume suffered from not having more light weight technologies like jQuery on it.
