France-Info has a new bulletin every 7 minutes, and in each of those I heard the journalists poked fun at the various politico's inconsistencies or outright lies.
These people were already public personae then, and they were in the media all the times - tons of unimpeachable sources are making a joke of their claims (Juppé was in the morning in Colombey, for a ceremony to mark de Gaulle's death, and the next day at the national assembly; his memoirs published a few years ago note that he was in Berlin on 16 November, but have no mention of him there before; one of the participants claimed they went to Berlin by train, after having heard 'in the morning' that things were happening over there; etc, etc... In the long run, we're all dead. John Maynard Keynes
Social software such as Facebook and MySpace aid surveillance by encouraging people to publish their interests and their friendship networks. They also aid sousveillance by making this information available to peer networks as well as to the authorities.
