How to Use Twitter in Higher Education

I decided that I will list my Twitter name on the syllabus for the class I am teaching that begins tomorrow, Project Management for Training. I decided to do this after reading an article in the Chronicle, Forget E-Mail: New Messaging Service Has Students and Professors Atwitter. As my class is in a continuing education certificate program, I am not sure how or what I will do with it, but I know nothing will happen unless I take the first steps.

While my class will only touch on technology, I am interested in listing the Twitter address and seeing where it may lead. Has anybody out there effectively used Twitter in an adult-oriented, non-technology focused class?
