C&C goes OpenID
I followed Simon Willison's instructions and, after creating an account with MyOpenID, Curiouser and Curiouser is now OpenID-compliant. This means that, in future, I can login to any open-id site with my blog url: http://matt.blogs.it/. I've tested it and it seems to work.
Some interesting points. A site using Open-ID can request additional information about you (which you can decline in whole or in part) and, at least with MyOpenID, you can maintain different profiles.
This is identity management that will work for geeks today and, I guess, after some Typepad/WordPress gloss it will work for everyone soon. Identity2.0 is, I guess, here.
