Last week Yahoo posted this blog.. They say:

“[It is] the companion blog for two libraries we’re proudly releasing today. The new Yahoo! Design Pattern Library offers our thinking on common interface design issues for traditional and rich Internet applications. The new Yahoo! User Interface Library is a collection of industrial-grade JavaScript utilities and widgets that enable you to efficiently get the most out of today’s powerful browsers. In both cases, these are the exact same things that power Yahoo! today.”

Kudos to them. They need to be more open than Google, more forthcoming on their APIs than Microsoft, and to start working more closely with Web developers. It is a good step.
