Instead of using social media to find new ways of basically selling chocolate bars to people (aka advertising), shouldn't the power of these wonderful tools be used for something good instead?
Obama used social media to mobilise a whole generation of people. This proves that the infrastructure can provide a great deal of momentum that cannot be stopped. And the more people that are connected, the more feasible it is.
Imagine using Twitter and other social media for:
* Starting an elite university for everyone
* Finance a microcredit system for the third world
* Starting direct-democracy movements
* Igniting resistances and revolutions, and overthrowing regims
When everybody is connected to everybody, the only thing that's required is will, and the only limitation is the imagination.
