I have developed a plugin that allows you to put your Buzz posts onto your WordPress sidebar (or anywhere, actually).
I used to have one of those widgets that shows your Tweets, It didn’t make sense to do that any more since I have been using Buzz more than Twitter. You can see the new plugin is in action on the right sidebar on this blog.
You can get the plugin here: http://www.admoolah.com/blog/index.php/buzz-feed/
