Audio from my talk this week is now available (just click on the [Audio] link). I hope to have video some time in the future. Also, just for fun, I wrote a scipt that added a back-channel for the conference. People would go here to add a comment, and I displayed the results in large text on the conference screen (you need a special login to display the large screen, because comments show once and only once). You can see the chat archives from my talk and Jay Cross's talk the following day. I am thinking of making this generally available for people to use - it's a very simple system, and all you need to do is display the web page. If anyone wants to use it, let me know.
