Dont just 'prioritize' one form of content.. Give us the choice to turn on and off the content I want to see and use.
Even further down this line of thinking about 'choice' is the hackability of the box.. 99% of people will use the default install but by allowing the box to be hacked the work thats done by geeks will open up totally new abilities, far beyond what the dev team dream up, and work as a win win all around.. Think of boxee box doing things like being nodes in a whole house audio setup, sync music playback (party mode), etc etc.. Open the box and let the geeks at it !! Boxee will win in the end from the development that happens.
