Glad to see you give reference to Mark Cuban in this, as I was reading it I was reminded of his blog.  One big difference I see between this post and Cuban is your much more positive outlook on providing free content and reaping advertising rewards.  It has amazed me how Cuban's viewpoint on free content has become very condemning, flat out stating that groups like youtube and hulu will fail.  

How a man amassed so much money using computers and software sales in a way others weren't would ever say something can't work is beyond me.  I would think he would be at the helm trying innovative ways of monetizing content.
