In this kind of web, it would also be quite possible for a single developer to run a site as big as Youtube without needing tons of up-front cost. Bandwidth is free from the perspective of the site developer, and doing some small finite amount of video conversion work for the network before your video starts playing could also be built into the smart contract. Not all problems scale well this way, but video conversion is embarrassingly parallel at the keyframe level AFAIK. Conversely, the site operator could just calculate the cost of running video conversions in AWS and spread this cost out to all users by increasing the page view fee slightly.
