Google Buzz is a relatively new service from Google that allows users to share information in similar ways to services, such as Twitter.
With Google Buzz’s popularity growing and there not being an official Google Buzz button that users can use to share information, Google Buzz created an official button that users can now use to share information on a variety of websites.
Some of the websites that you may see this button on include: YouTube, MySpace, GigaOm, Mashable, Meebo, as well as more websites and services.
If you would like to add a Google Buzz button to your own website, you can do so by going to Google Buzz’s “Stuff” webpage and and then copy and paste the code into your website.
There is an official blog post on the GMail blog about the Google Buzz button.
