Starting today, you'll see these buttons around the web on participating sites including: The Washington Post, The Huffington Post, Glamour, YouTube, Blogger, MySpace, GigaOM, PBS Parents, PBS NewsHour, The Next Web, TweetDeck, SocialWok, Disqus, Vinehub, and Buzzzy. Mashable and TechCrunch have updated their sites to use these new buttons too.
A number of sharing platforms, including ShareThis (pictured below), Meebo, Shareholic, AddThis and AddtoAny have also incorporated the Google Buzz button into their sharing functionality, so you'll see Buzz listed as a choice when you go to share something on many other sites around the web as well.
