So I tired to make my blog appear in Google Buzz. I tried the <link> tag that was described in the Google Buzz API Documentation. No dice though. I finally found instructions though.
Adding wordpress.com blog as connected site in Google Buzz
Works like a charm. If you’re not a wordpress.com site you can add the <meta> tag by going to the theme editor and inserting the tag in the header.php file (assuming that the theme is created properly).
Yay!
