Backchanneling

Got this from a TCEA newsletter recently:

 Instead of ignoring the backchannel, leverage its power.Tapping into the backchannel lets you tailor and direct your presentation to the audience in front of you, and unifying the means the audience can share insights, questions, and answers with each other and not just the presenter. Below are some great backchannel resources:
 * __ Today's Meet __
 * http://www.wallwisher.com
 * __ Meeting Words __
 * __ Corkboard __
 * __ Pindax __
 * __ Twiddla __
 * __ Backchan.nl __
 * __ Using the Backchannel in Your Classroom __
 * __ How to Present with Twitter (and Other Backchannels) __
