"Web 2.0" technologies--such as Web logs ("blogs"), social networking Web sites, video- and multimedia-sharing sites, and "wikis"--are increasingly being utilized by federal agencies to communicate with the public. These tools have the potential to, among other things, better include the public in the governing process. However, agency use of these technologies can present risks associated with properly managing and protecting government records and sensitive information, including personally identifiable information. In light of the rapidly increasing popularity of Web 2.0 technologies, GAO was asked to identify and describe current uses of Web 2.0 technologies by federal agencies and key challenges associated with their use. To accomplish this, GAO analyzed federal policies, reports, and guidance related to the use of Web 2.0 technologies and interviewed officials at selected federal agencies, including the Department of Homeland Security, the General Services Administration, and the National Archives and Records Administration.
