Blogs and Ender's Game

Has anyone else noticed this? In Ender's Game, Orson Scott Card predicted blogging, and predicted that it would become a major force in politics and society. Valentine and Peter, Ender's siblings, create blog personas that comment on important world events. Eventually they become so influential that Peter can be voted president of the Hegemony at the age of 15 or something. I find it so interesting that irl blogs are just beginning to influence world opinion, journalism, elections, etc.
