This is a wonderful and well thought proposal! Connecting and exchanging is so powerful in helping movements and communities support each other and build from each other's experiences and knowledge. The spontaneous and decentralized nature of it poses often a challenge for the wealth of information to travel far. Even more so in an era when long distance travel is often a concern in the face of the need to lower our carbon emissions, a tool such as this could allow a much effective degree of global interaction and traceability of the immense tapestry of grassroots initiatives and, a pool for solidarity among the struggles.
