NASAโ€™s embrace of Twitter, Facebook and other social media applications helped the U.S. space agency place first in the Digital IQ Index for the Public Sector, a new annual survey released Nov. 23 by the George Washington University School of Business and digital think tank L2.

NASA was assigned a Digital IQ score of 184 and praised by the studyโ€™s authors as being โ€œin its own stratosphereโ€ when it comes to using social media and the Internet to engage the public.

The White House, which was praised for its embrace of YouTube and using open-source contests to solicit ideas for balancing the budget, ranked second in the survey with a Digital IQ score of 158.

People for the Ethical Treatment of Animals came in third with a score of 149, and the U.S. Army, recognized for a highly rated iPhone application, came in fourth with a score of 145.
