This document discusses social networks and how they apply to the eTwinning online community. It defines what social networks are and how they are represented visually through nodes (actors) and ties (relationships between actors). The document then examines eTwinning as a social network, noting that as of 2008 it included over 45,000 teachers from 30 countries working on over 8,000 projects. It explores how social network analysis can reveal tightly connected groups, isolated groups, and influential members who span different connections. ETwinning ambassadors are encouraged to make connections and participate in order to strengthen the network and introduce new opportunities.
