I discovered an interesting new site today called Buzztracker. The site refers to the Google world news directory and constructs a world map superimposed with differently sized red dots representing the number of stories associated with geographical locations. Differently shaded lines between dots represent the stength of relationships between stories associated with those locations.
This provides a very interesting depiction of what's happening in the news around the world. Even more interesting is seeing how the relationships change from day to day as new world events unfold.
