I think that this is an excellent example of how to use the power of social media for a good cause.
Today is the 23rd World AIDS Day. In order to raise money for the cause, the organization Keep A Child Alive is running a campaign called 'Digital Death".
Famous celebrities like Katie Holmes, Usher, Jay Sean, Kim Kardashian, Ryan Seacrest, Alicia Keys, Jaden and Willow Smith, Serena Williams, Swizz Beatz and more have stopped posting on their Twitter and Facebook profiles until 1 million dollars is donated to BuyLife.org.
