Found this interesting quote on Tech News World story on "Where Have All the Avatars Gone":
"Over 2,000 global enterprises, 600 universities, 35 international governments, and several divisions of the U.S. federal government -- including the Departments of State, Homeland Security, NOAA, NASA, Army, Navy and Air Force -- now exploit Second Life technology to connect with stakeholders around the world, communicate complex ideas, train and collaborate."
-- Kim Smith, chief operations officer and vice president of World2Worlds
It's an interesting piece about how many businesses are using virtual worlds for various applications, but many are not visible because they use it for private meetings, corporate training, inter-office collaboration and other non-public uses. If this is the case, I wonder how education and nonprofits can benefit from these new practices?
