The central idea that drives these knowledge exchange networks is the conviction that everybody can teach and learn something, and, therefore, it is a good idea to share and exchange knowledge.
The goal of these networks is to give and receive knowledge beyond commercial exchange. They are excellent tools for building community and for the advancement of reciprocity. People involved in social transformation programs are mainly concerned with the distribution and spreading of knowledge. Usually, these initiatives are started together with other educational projects, either online or on a face-to-face level, and are linked to local neighborhood endeavors.
