Being a Keynote user for my presentations I was thrilled to find this tool. In some scenarios it would be fantastic to update Twitter with bits from a presentation and include a hashtag for folks to follow. Keynote Tweet from Ideo Labs watches for tags in your presentation notes (visible to the speaker) and sends a Tweet and optionally hashtags (like #mypresentation) and an @username of the text found between [Twitter] and [/Twitter].

I have written before about the excellent versatility in Keynote for presenters and with this widget - you can integrate the social community at large in your public speaking. There are a lot of e-learning folks harnessing cloud technology to reinvigorate conferences and meetings - this provides a simple tool for anyone engaged in public presentations to put their foot in the waters and take it for a spin. You can go back after the fact and search for your hashtags on Twitter. Take not that Twitter does not archive hashtags for very long - so look for your Tweets within a few days of your presentation. If folks were monitoring your hashtags then you will also find the conversation they started based on your posts.
