Great Lectures for Free - elite world of humanities goes open source

On ABC7 local news I heard a news story about a fabulous free opportunity. You can download lectures from some of the best professors at the best universities in the US. Go to school web sites, like openculture and a special section of iTunes known as iTunes U. I have seen lectures like these for sale on tape for hundreds of dollars, but had no idea they are available for free online. Woo-hoo!!
