Social networking allows individuals to construct public profiles, connect with other users, and view their connections. Popular services include Facebook, YouTube, and LinkedIn. While social networks allow sharing information and strengthening relationships, they also present privacy and security risks if too much personal information is shared. Notifications from social networks may also only share positive information.
