OpenIDAn OpenID provider should catalogue the sites that a user logs into and automatically construct a homepage for them. That way, not only do the users have the convenience of having their favourite websites automatically bookmarked and readily available, but (with a little help from the consumers), they don’t have to log into the individual sites at all.

This is exactly how I envisioned OpenID to work. I'm glad to see this thinking is out there and hopefully, in the next year or so, become a reality.
