Many business presentations these days involve more than just the spoken conversation between the speaker and his or her audience.Using Twitter and other electronic media,audience members often carry on their own parallel communication during a presentation via the backchannel,which presentation expert Cliff Atkinson defines as "a line of communication created by people in an audience to connect with others inside or outside the room,with or without the knowledge of the speaker." Chances are you've participated in a backchannel already,such as when texting with your classmates or live-blogging during a lecture.The backchannel presents both risks and rewards for business presenters.On the negative side,for example,listeners can research your claims the instant you make them and spread the word quickly if they think your information is shaky.The backchannel also gives contrary audience members more leverage,which can lead to presentations spinning out of control.On the plus side,listeners who are excited about your message can build support for it,expand on it,and spread it to a much larger audience in a matter of seconds.You can also get valuable feedback during and after presentations.
