I've been considering creating a Twitter account for my students. It would obviously be a protected account so only my students could access it. I'd use it to remind students of upcoming assignment dates, online lectures and the like. It would also be a way for my technology savvy but socially wary students to contact me outside of my usual manner (telephone, email, in-person visits). Has anyone in a more traditional setting starting using Twitter? If so, how has it gone?
