Tweeting Teachers

As a teaching tool, PowerPoint can be awful. Is Twitter any better? One promotes passivity; the other, connectedness and interactivity (unless you follow people like us, who are about as responsive as a dining room table). The Chronicle of Higher Education raises an interesting question: should professors be tweeting with their students? Or is it a poor substitute for face-to-face interaction? Of course, some say brevity is the soul of wit, and 140 characters is very, very brief. [%comments]
