Tweeting During a Lecture..To do or not to do?

This week we are going to be having an online discussion using Twitter.  We will discuss the below article about tweeting during a lecture.  Would tweeting in class be distracting or actually helpful to foster in-class learning.  I'm debating whether I should incorporate in-class tweeting next semester.  I'm leaning towards yes.  I'd love your opinions/advice on what you think.
