IDEO Labs » Keynote Tweet: Participate in the backchannel of your own presentation

So what if your presentation software could send tweets on your behalf that were timed to the slides of your presentation? You could effectively simulcast your presentation through the backchannel as a part of the conversation, adding ‘more info’ links, credits, or anything else you could imagine…

Enter Keynote Tweet, a simple open-source script that provides the capacity to participate in the backchannel by combining Twitter with Apple Keynote. All you have to do is add text wrapped in [twitter] and [/twitter] tags in the presenter notes section of a slide. When that slide comes up in the presentation the script grabs that text and sends it to Twitter on your behalf.
