"Open"ing up IDs

Finally, someone who's serious about OpenID - a great first step:

Yahoo!'s initial OpenID service, which will be available in public beta on January 30, enables a seamless and transparent web experience by allowing users to use their custom OpenID identifier on me.yahoo.com or to simply type in "www.yahoo.com" or "www.flickr.com" on any site that supports OpenID 2.0. Alternatively, web sites that accept OpenID 2.0 will be able to add a simple "Sign-in with Your Yahoo! ID" button to their login pages that will make it even easier for their users.

Now if we can just find ways to splice in the social graph and access the same data consistently across sites.
