A social semantic network provides for the efficient distribution of digital objects between users of that network. People in the network are connected by labeled edges that define relationships. Any person can create content in the form of particles, and by labeling that content, can determine how that content is distributed through the network. Labeled particles travel through each node in the network based on comparisons of the particle label with each edge label when exiting that node. Propagation can be controlled by the person at each node through which the particle travels or, alternatively, the system can be adapted to propagate particles one or two nodes at a time. Thus, a decentralized push-based system for distributing content is achieved without extensive regulation of that which is "appropriate" for consumers.
