rel=”me” – really interesting use of XFN microformat to provide security

It turns out that you can claim your blog on Technorati by creating a post (such as this one) and including a link to the claim on Technorati, like so: Technorati Profile

This link’s HTML is a XFN microformat, in that it contains the attribute rel="me":

<a rel="me" href="http://technorati.com/claim/uqv8b6pg22">Technorati Profile</a>

This seems like a genius method of proving that I am authorised to claim this blog, since I had to get into this system to do it. No OpenID, no OAuth, just a hyperlink. I’m sure timbl would approve.
