The ability of social media tools such as Facebook and Twitter to relay news around the world at breathtaking speed has been well documented this past year, particularly when these sites first provided video of the Iranian election protests, and the outpouring of emotion and money for Haiti relief.

They will spend five days—beginning Feb 1—locked away in a house in the southern regions of France. “Our aim is to show that there are different sources of information and to look at the legitimacy of each of these sources,” said one of the participants.
