Social Media Use by Professors

The Chronicle of Higher Education's "Inside Higher Ed" blog reports on a recent survey about the use of Web 2.0 by college professors. http://www.insidehighered.com/news/2010/05/04/socialmedia
While 52% of professors in the survey reported using Web, the use was uneven: one fifth of those reporting use directed their students to YouTube videos, but less than 5% used Twitter. FaceBook and LinkedIn were used mainly to connect with colleagues. All professors did agree that social media are supplements to their teaching, and not replacements.
