An anonymous reader writes: Iceland is using Facebook to rewrite its constitution: citizens can use the social network to make their own suggestions, engage in online debates, or follow the proceedings in real-time. Two thirds of Iceland’s population (approximately 320,000) is on Facebook, so the constitutional council’s weekly meetings are broadcast live not only on the council’s website, but on the social network as well. “It is possible to register through other means, but most of the discussion takes place via Facebook,” said Berghildur Bernhardsdottir, spokeswoman for the constitutional review project.
