Webby Awards: Twitter, Facebook, Others Nominated For People's Special Achievement For Social Change Award (VOTE)

Nothing will replace the immeasurable power of a protest that gathers thousands of people in a city square. But a number of organizations and social networking websites have given activists the tools they need to raise awareness around critical social issues, thus giving them the knowledge, and imbuing the passion, to stand up and lend their voices to a cause.

To recognize the initiatives that play such a critical role in galvanizing the masses, the Webby Awards panel has chosen five nominees for its inaugural People’s Special Achievement Webby for Social Change. The honor recognizes those who have played “an integral role in advancing and organizing the masses in 2011’s sociopolitical climate.”
