One of the less spectacular announcements of last week, but not less important was the commitment from Windows Live ID to support the OpeID digital identity framework. That means that you soon will be able to use your Windows Live ID account to sign in to any OpenID Web site.
Details on the announcement on the Windows Live ID team blog.
The commitment of +400 million Live ID’s is seen as a huge support for OpenID. And that was not all, 2 days after Microsoft also Google announced they will support OpenID.
