Yes, good point. As a network operator you have to appreciate the fact that very few people can come up with what most people will perceive as good looking web page. Moreover, it is nigh impossible to coordinate millions of people to produce designs that are coherent with the rest of the site.

Imagine a city where councils allow full freedom of styling and architecture, and home owners are given the tools to DIY-design their houses. The place won’t look good. It won’t even be eclectic or organic. It would be a mess. Black bulky concrete cubes next to adobe hobbit-dens next to tin warehouses next to junkyards and caravans is what you’d get.
