An incredibly packed show this week. First, to Moldova to find out what role Twitter and other social networking sites have played in the protests there. Then to France for Urban Pac-Man! Also, two hits on tech and security. Are there Russian and Chinese spies pinging the US electricity grid? And are extremist websites being hosted on servers in the United States? Good questions. We also hear about an award-winning solar cooker, and about GoogleLitTrips.
