@silverlight, and additional thoughts
Siverlight isn't the problem, and I think that, that comment is just distractional from what the story is about. After all you've probably installed Flash player from Adobe, countless times, if you go do different sites and get told you need the latest version of Flash installed to play the content.
Gates'y in his philantrophic mode has IMHO, done something very worthwhile, and I don't care if he monopolises all of those lectures if he provides them for fre, albeit even if you need to install Siverlight.
Perhaps he could do the same for all of the Beeb's Christmas science lectures, which have also been a valuable contribution to increasing the popularity of science.
If your only beef about this story is having to install Silverlight, then I feel sorry for you. The focus should have been on the science part of the story, not attached to the link you obviously clicked to find that out. I know, especially in this day and age, how increasingly hard it is to not be cynical, but I honestly believe, this is a story without any cynicism intended.
