I Twibboned.

Twibbon is an application for Twitter, Facebook and Myspace that puts a little graphic on your avatar supporting a cause you believe in (or an entertainer, or any number of things). I made a no GMO Twibbon. If what you eat matters to you, and you'd like to see legislation for GMO labeling, consider wearing this little doohickey on your avatar in any of these apps -- or find a cause that matters to you and support.
