Just set up a block on this site with some links from my opml file with XFN rel attributes, then I posted my URL on www.rubhub.com to get crawled.  I wonder where this standard/proposal will go.  Possibly nowhere, but it might be interesting to have RubHub's crawler create an SNS from what's out there on the web.  .Text's link sections don't allow one to add rel attributes to the anchors so I added the HTML to the "

Incidentally, if you're inclined, you can add a XFN "contact" link to me like so:

<a href="http://blogs.msdn.com/tmeston" rel="contact">Tosh Meston</a>
