How to add your site's feed to Google Buzz
Google Buzz Profiles use the Social Graph API to verify your feeds — this link shows you how to add some markup to your blog, Tumblr, or other site to add it as a verified link to your Google Profile and to Buzz.
It should look something like this:
<link rel=”me” type=”text/html” href=”http://www.google.com/profiles/your.username”/>
