The dynamic nature of the social networking site means that it is constantly evolving, thus levels of privacy are simultaneously shifting as well. Even throughout the short duration of this research study, Facebook added two new major features to its service: “Places I Check Into” and “See Friendship.” The Places application allows users to virtually check-in to a real-life location, alerting all their Facebook friends of their current position on the map. This raises major safety concerns, as Facebook users could exploit this information to track down and find an individual. Future studies on the Places application could determine its level of privacy and safety and investigate users’ opinions of its appropriateness on the Facebook site. The “See Friendship” feature, which replaced the “Wall-to-Wall” feature, allows Facebook users to see
every interaction that has taken place between two mutual friends. Similar to the introduction of the News Feed in 2006, some users feel that this is a violation of privacy, allowing others to see all of their personal interactions. Future research could determine how people use this new feature, and whether or not they feel it compromises their privacy.
