Tweeting, PowerPoint, and Knowing Your Audience

I've noticed a new trend in class. Tweeting about the professor's lecture effectiveness (i.e. all my student's say mine are great!). This is one of the reasons why I encourage my students to follow me, so I can review these later. I came by an article recently that suggested that it is important to know your audience and remember they might be tweeting while you present (not to mention the importance of updating your lame PowerPoints). So, this is a new way to heckle the professor without her or him knowing it. For me, the bigger challenge here is how to make your classes more technologically aware. I recently received a message from my daughter who was in her class at CU, the message was a question from her professor that encouraged the class to tweet, instant message, or text people they knew and ask them a question concerning meaning making and hermeneutics. Her class received almost 200 responses throughout the class period. Heather Buckley concludes, 'Presenters beware – twittering will be around for some time, if you have a large audience be sure you know them well and give them what they want. Even if you know all this and are a great presenter following your audience reaction on twitter can only be a good thing, feedback is a good thing and now it is happening real time' .

So, what do you think about tweeting while in a lecture? Or better, what would tweeting while in church offer pastors looking for feedback? On a related note, has anyone started using Twitter lists effectively? If so, point out some good examples. How could Twitter lists be used in Biblical Studies?
