I thought one of the big lessons of OpenID is that the non-technical world thinks FQDNs are for web sites (or something you type into Google!) and user@host is for identity? I still have trouble explaining that jay@jay.fm is my entire e-mail address, and that there is no .com at the end of it. I think there was a point where everybody wanted to blog, and thus might have an URL that they considered "me", but that's gone away with Twitter and Facebook. Come to think of it, many people have a Facebook claimed URL, but I've never typed or clicked one, and I don't even know my own.
