A piece of useful software for Mac-using teachers

I gave a lecture yesterday on animal minds, and in the course of it tried to show some YouTube videos in Keynote by linking to the pages (tool using crows, by the way, and the excerpt from Life of Birds by Attenborough on Japanese crows using stop lights to get nuts they dropped under car tyres, very cool. The students loved it). Great technical problems.

Today (of course, a day late!) I came across TubeTV which downloads the Flash videos for embedding in Keynote directly. Works, is free and is very useful for when you don't have enough material for the entire lecture.

Highly recommended (as, of course, is the new Keynote from Apple: I have recovered Powerpoint presentations munged by PPT by opening them in Keynote, and it is a much better interface).

The DNC does not always have a keynote speaker. Sometimes there is a speaker that can be thought of later as such, but was not necessarily labeled "keynote" at the time. So this list can certainly be argued with.
By popular request, I've uploaded the slides I used in my talk at NDSU. I fear they won't be very useful; you can see the structure of the talk, but what I was saying was the meat.
The second Online Philosophy Conference has begun, and the first week's presentations are up.
OK, quick question! As regular reader will know, I have migrated to a Mac. I have tons of presentations in Powerpoint which, while written on a PC, open seamlessly on the new machine.
