Has anyone used the Y! dev tools they so graciously went public with? I've primarily used the page layouts for one major reason - they are cross browser, w3c compliant, and heavily tested by Y!. Granted, I've had to go in and modify every layout to get it suited to my taste, but I was very happy they decide to go public with this stuff. And of course shortly after this, G decides to release their own web dev platform. Gotta love benefitting from their competition
