The second most interesting announcement out of PDC this morning is that Windows Live ID is becoming an OpenID Provider. The information below explains how to try it out and give feedback to the team responsible.

This is awesome news. I've been interested in Windows Live supporting OpenID for a while and I'm glad to see that we've taken the plunge. Please try it out and send the team your feedback.

I've tried it out already and sent some initial feedback. In general, my feedback was on applying the lessons from the Yahoo! OpenID Usability Study since it looks like our implementation has some of the same usability issues that inspired Jeff Atwood's rants about Yahoo's OpenID implementation. Since it is still a Community Technology Preview, I'm sure the user experience will improve as feedback trickles in.

Kudos to Jorgen Thelin and the rest of the folks on the Identity Services team for getting this out. Great work, guys.

UPDATE: Angus Logan posted a comment with a link to the following screencast of the current user experience when using Windows Live ID as an OpenID provider experience
