In an interesting article written by the Politico's Victoria Esser on the use of social media in advancing U.S. public diplomacy, Esser explores the question of whether or not President Obama should use the same "technologies that helped him generate huge grass-roots support in his presidential campaign to build support for America on the world stage." Although not mentioned in her article, the State Department has already made its own foray into "public diplomacy 2.0" with the launch of its own social networking site, ExchangesConnect, and its blog, Dipnote.

How do you think these and other social media tools can be used to advance U.S. public diplomacy?
