Another social networking tool that is available for advocacy is YouTube. It is powerfull because your message is fuller and has more meaning for the viewer. It is easier to evoke emotion and foster action when someone sees a video that moves them.
One example is the End Waitlists Now campaign that used a video made by a volunteer. During the weekend campaign it recieved a 1000 hits which is a pretty big deal for a home-made video. You can edit the movie using Windows Moviemaker or Roxio.Social tagging: Web 2.0 > Web Advocacy
