iTunes Huh

iTunes U is a good idea and some of the lectures are good...but then you get the ones that sounds like... "This is an important point ....[scratch scratch scratch scratch on the blackboard] ...and here...[more writing on the board]...is another important point....and this point connects [line drawn on board] to this point...does that make sense? Fine, moving on...[more writing on board]...." Someday these lectures might be made in a way that is optimized for iTunes...then we could just pay for college credits through the iTunes Store.
