From the just released 2009 Horizon Report:

Information technologies are having a significant impact on how people work, play, gain information, and collaborate. Increasingly, those who use technology in ways that expand their global connections are more likely to advance, while those who do not will find themselves on the sidelines. With the growing availability of tools to connect learners and scholars all over the world — online collaborative workspaces, social networking tools, mobiles, voice-over-IP, and more — teaching and scholarship are transcending traditional borders more and more all the time. (Emphasis mine.)

Another pebble for the pile…
