a post on presenting with an active backchannel: but what if you were twittering during your own presentation? you could create a depth of interactivity that wouldn't otherwise exist... participating in the backchannel to unpack your ideas, reveal sources, create connections, explain uncommon concepts. twitter plugin for powerpoint: where are you?

PS: this is why we need activity-based computing and a more nuanced awareness of context.
