This document discusses social networks and how they apply to the eTwinning online community. It defines social networks as structures made up of nodes (actors like teachers and schools) and ties (relationships between nodes like friendship or collaboration on projects). The document examines how eTwinning exhibits characteristics of a social network, with nodes, ties, and metrics like centrality and betweenness that can be visualized. It encourages eTwinning ambassadors to actively engage in growing their local networks and connecting other members to help the overall eTwinning network.
