Yahoo has talent, and YUI was the best library out there
No not really, and not it wasn't. Yahoo's UI library didn't really offer any radically new concepts. It was a recap of other libraries. For example instead of TinyMCE you could use YUI's editor which did almost the same thing, instead of jQuery you could use YUI's dom code, and so on.I didn't really expect anything amazing from Yahoo. They'd need to come out with something truly extraordinary to make me pay attention. And given their webpage hasn't changed since 1998 I doubt that will ever happen.
