In the reported network compositions (Figure 1), we saw that Facebook friend networks and audiences are primarily composed of strong and weak ties. This may be an artifact of Facebook's origins as a limited network, with a normative orientation towards real-world, close friends [20]. Reading into the findings, it is possible that weak ties represent the functional periphery of the undergraduate Facebook network; having an expectancy violation by weak ties may generate substantial privacy concerns motivating boundary coordination. The small size of the outsider audience lends credibility to this notion, as most respondents do not perceive outsiders as part of their functional audience.
