Ned Miller does not take security lightly. As director of campus safety and emergency management at the Des Moines Area Community College (DMACC), any threat requires serious consideration. As community college administrators adopt a more proactive approach to campus safety, many institutions are experimenting with emerging technologies, including potential applications for social media, using Twitter and Facebook to notify students and faculty of closings, emergencies, and public safety issues on campus. Social media is also being used to assess what Alvin Winkler, chief of public safety and security at Baltimore City Community College (BCCC), calls the "mood" of certain factions on campus. Though viewed as a good fringe benefit, experts say the technology has not advanced to the point where it should be viewed as a primary security measure.
