"As the sharing economy picks up momentum, its reach has become global. In cities and towns around the world, people are creating ways to share everything from baby clothes to boats, hardware to vacation homes. There are also groups emerging that consciously identify with the big-picture sharing movement. These groups focus on education, action and community-building, and advocate for a cultural shift toward widespread sharing.
From neighborhood-level cooperatives to global organizations, these groups work to bring sharing into the mainstream. They see sharing as a new paradigm; a means to a more democratic society, and they understand that sharing is not a new fad but an ancient practice that technology is reinvigorating."
