One of the great things I have learned from David Warlick (and have only had a chance to use it once, but loved it) is to foster the "back-end chat." So many times I've heard - "Close your laptops now. OR Turn off your monitors." We are so afraid of what THEY will do if we can't have their undivided attention.
So how do we foster multi-tasking computer users WITHOUT losing the dreaded "time on task." You create a mechanism for your audience to discuss issues DURING the presentation. You foster the "back-end chat."
David has done this and then afterwards interjects his own comments and posts the chat. Today, I got around to actually reading the chat and clarifying some issues.

and happy Backchatting!
(Oh and I used a program called Pladeo to do this - instead of the Ajax chat client David used.
