Agencies have launched social networking applications at such a fast pace that government officials said on Friday that they plan to add more applications, such as Apple’s popular media store iTunes and the career-networking site LinkedIn.

The government also is negotiating agreements with social publishing site Scribd and commenting platform Intense Debate, said Martha Dorris, acting associate administrator for the General Services Administration’s Office of Citizen Services and Communications. The federal government has signed modified terms of service agreements to allow agencies to use social media sites Flickr, Facebook, YouTube, Vimeo, Slideshare and AddThis, among others.

The response to the agreements has been excellent, Dorris said. Agencies have set up Facebook profiles, Twitter accounts and YouTube channels to share information with the public. “We’re looking at taking information wherever citizens go to get information,” she said, adding GSA will consider adding more social networking sites, depending on requests from agencies.
