Much that I cringe at big business, I have to hand it to Pearson for their smart marketing. I think a lot of this project's appeal is in making OER easily searchable and accesible from one central location. I know there are ways to do that for free out there, such as OpenDOAR, but Pearson's looks a lot slicker. Of course Pearson's own content is readily visible in searches, at least according to the screenshots. This does not seem to be an unbiased OER search engine.
Pearson ran a survey about the use of Social Media in teaching, here is the summar:
■64.4 percent of faculty use social media for their personal lives, 33.8 percent use it for teaching
■41 percent for those under age 35 compared to 30 percent for those over age 55 reported using social media in their teaching
■Faculty in the Humanities and Arts, Professions and Applied Sciences, and the Social Sciences use social media at higher rates than those in Natural Sciences, Mathematics and Computer Science
■Blogs and wikis are preferred for teaching, while Facebook or LinkedIn are used more for social and professional connections
■88 percent of faculty, regardless of discipline, reported using online video in the classroom
