A majority of Facebook users say they connect to the social networking site from work, but 73 percent have not "friended" their boss, according to a new report from F-Secure. More than half (58%) of Facebook users said they visit the site at least occasionally at work and 77 percent report they actively use the privacy settings on the site. "We're finding that Facebook users are more privacy savvy than some experts assume," said Sean Sullivan, F-Secure Security Advisor.
