I've been working on adding OpenID support inside Google as a 20% project for a while now. It took some evangelizing, but our first OpenID project, commenting in Blogger, has finally launched!
For the OpenID geeks out there, we've turned Blogger into a consumer, aka relying party. It has full support for 1.0 and 1.1, and partial support for 2.0 draft 12. (It's missing XRI-based discovery.)
OpenID commenting is currently supported in Blogger Draft, ie beta, but we'll roll it out to all users soon. Keep an eye out for future OpenID projects...
