I’m getting around to finishing my final tasks for the INFORMS 2006 conference (which I thought went great!). A number of plenary speakers have made their presentations available: if you were at the conference, you can relive the excitement; if not, you can see what you missed.
It would be even better if everybody post his presentation file.
I agree: it would be great to have pointers to all of the talks. We tried to do that in the late 90s through INFORMS Online, but the response was terrible. With 3200 talks now, the most we can hope for is that people post things on their own web page, and some people do.
