Interesting article - conclusions a little vague, but research is interesting. Hope no one used this before (did not see reference if they did)

Cutting-Edge Social Media Approaches to Business Education: Teaching with LinkedIn, Facebook, Twitter, Second Life, and Blogs, Charles Wankel, St. John's University (Editor) (ISBN: P1617351164) Is a collection of several articles, the most interesting being how in their courses instructors incorporate different social media with skills and approaches to collaborative learning. Wankel points out that new media share text, images, audio and video material rapidly and interactively. Examples and cases of how instructors around the world are meaningfully incorporating them into their management, marketing, and other business courses are detailed.

The book An Administrators Guide to Online Education by K. Shelton and G. Saltsman (Information Age Publishing, ISBN13:978-1593 114244) is endorsed by the US Distance Learning Association. The book is a good basic reference for establishing an online program and managing/administering the program.
