Twitter or Email?

Several weeks ago I blogged about Leadership By Email and Other Dumb Ideas, where I said "Email appears to be here to stay." One blogger says not: Is e-mail on the way out? | RedEye | iPhone, Therefore I Blog. He suggests that Twitter is taking the instant communication world by storm. Just to reaffirm my basic point: You cannot be leader using email OR Twitter as your dominant mode of casting vision, training, equiping -- as your dominant mode of leading. Face time people is crucial.
