3DTLC Tweeting

I have never seen such tweeting, blogging, yamming, emailing, sms'ing direct and live from a conference in all my life. Its crazy. Over 10-20 questions are being posted live in parallel with all presentations to Twitter using the private channel #3DTLC hash tag which you can monitor in realtime using tools for example like Tweetdeck. The presenter checks every few minutes who has posted questions and answers 3-4 before moving to the next section. This is social media in action. Now to bring it to the classroom?
