For anyone who thinks this is a distraction, I can only offer my own experience with the game. Prior to the last keynote, I actually found myself reading Rich Halverson’s CV and an abstract of his book to prepare my keyword bets. I was more engaged than ever in the sessions, trying to detect trends I could use for future bets in the game. So while this is clearly anecdotal evidence, the game worked for me. LibraryRemix points out that because this activity develops skills in trendwatching, it could be powerful in schools as well:

What if your students were compelled to pre-analyze a discussion, predict trends (places they believe their peers will focus their attention during that discussion) AND perhaps empowered to influence those trends themselves, simply by participating in the conversation?  Heady hands-on experience!

I have hung out in many a Twitter backchannel at plenty of conferences (in case you haven’t heard, I’m the reigning Grand Poobah of Social Media from TTIX 09). BackChatter is the most effective, engaging idea I have seen for encouraging meaningful activity on Twitter. Kudos to all who were involved in this project! I hope you will share your project with other conference organizers.
