Federal Computer Week: “Twitter has quickly evolved from social media novelty to critical communications channel. This list shows which federal agencies have built the biggest audiences, and where the growth has been fastest over the past year. The data [in this article] was compiled by OhMyGov, a media and technology firm that specializes in providing advanced media intelligence for government agencies, congressional offices, lobbyists, and businesses working with government. Please note that for many agencies, follower totals for multiple Twitter accounts were combined to provide a better sense of total reach. All counts are as of Aug. 31, 2012.”
