This is offtopic, but I'm really impressed with whoever designed InfoQ's interface for watching presentations and interviews. Being able to watch the slides and the presenter simultaneously in separate panes is an approach I wish more sites would copy. I also recall a recent interview I watched on their site: there was a list of topic summaries below the video, and you could click on any of the topics in the list to skip right to that point in the video. It's a very functional user interface as these things go.
