A new and empowering way of looking at and organizing social change! How can we move from serving soup until our elbows ache to solving chronic social ills like hunger or homelessness? How can we break the disastrous cycle of low expectations that leads to chronic social failures? The answers to these questions lie within Momentum, a fresh, zestful way of thinking about and organizing social change work. Today's digital tools--including but not limited to e-mail, the Web, cell phones, personal digital assistants (PDAs), even iPods--promote interactivity and connectedness. But as Momentum shows, these new social media tools are important not for their wizardry but because they connect us to one another in inexpensive, accessible, and massively scalable ways.
