Since I complained about identity management on my blog, the least I can do is try out a proposed solution.
trueg's web post alerted me to the existence of a new standard, WebID. So I've added a link to my FOAF profile (Friend of a Friend), and somehow that will tie into my public-key certificate for my identity. Damn, this is complicated. It's sad and funny that his blog post about identity won't let me identify myself with OpenID or WebID, instead WordPress uses its odd "email lite" Gravatar identity service. I've set up an identity on that too.
