Already some days are working Google Buzz. I made short search on Google for possibility to add Google Buzz button to Blogger template. As I didn’t find it on first page, I decide to rewrite some of previous Blogspot template code, which I made earlier.

So here it is: (live example: http://mediabox4b.blogspot.com)
<a expr:href='&"http://www.google.com/reader/link?url=" + data:post.url + "&title=&" + data:post.title + "&srcTitle=" + data:blog.title+ "&srcURL=" + data:blog.homepageUrl ' rel='nofollow' target='_blank'>+add to Google Buzz</a>
put it near data:post.body
Made with MediaBox.lv / Umbrovskis.com
Where
url=data:post.url – post URI,
title=data:post.title – post title,
srcTitle=data:blog.title – post source, You may also use data:blog.homepageUrl,
srcURL=data:blog.homepageUrl – source home page.
And Google Buzz button for WordPress blogs:
<a href="http://www.google.com/reader/link?url=<?php the_permalink() ?>&title=<?php the_title(); ?>&srcTitle=<?php bloginfo('url'); ?>&srcURL=<?php bloginfo('url'); ?>" rel="nofollow" target="_blank">+add to Google Buzz</a>
Put this inside WordPress post loop.
