I am only dimly aware of what openid is/how it works.
All of a sudden I've got a livejournal, blogger, and flickr openid. So how would I merge them?
For instance, I log into a foo.com via the livejournal openid to leave a comment. The next time I log in, about 3 months later, its via my blogger openid.
I'm the same person, but how do I tell foo.com that?
The only answer I really have is "OpenID + FOAF", but only livejournal and one or two others bother outputting this.
