The news out of Yahoo! this morning is that they have released their User Interface Library which inluces a set of utilities and controls, written in JavaScript under a BSD license and their Design Pattern Library under a Creative Commons license. On top of that, they also have started up the Yahoo! User Interface Blog to evangelize both releases. A cursory look shows that some of these tools are right out of the new Yahoo! Email beta and Yahoo! Maps beta (as well as some of the My Yahoo! interface).
