This document discusses social networks and education. It notes that social networks allow individuals to create public profiles, form connections with other users, and view their connections. The main difference between social networks and other communication is that social networks make social connections visible. Social networks can help sustain strong and weak social ties as people move between communities. They can also foster peer connections for young people based on interests rather than just geography, giving access to influential information and relationships to build a greater sense of belonging and persistence in school.
