I’ve just stumbled over two great websites based in the US devoted to helping people share and showing them how to do it: the sharing solution and shareable.net.
The sharing solution is run by Attorney Janelle Orsi & Attorney Emily Doskow and is devoted to showing people how sharing can not only be economically advantageous, but also fosters community. I’ve realised over the last three years of running yours2share that once people start sharing, the pleasure at the creation of a new community based around something you love or feel strongly about, is far more important to them than the economic or environmental benefits.
