Zhang just proves the point that the mother zucker realized from day one that:
* Fakebook could be a socially responsible publisher, like print and TV, except the staffing/infrastructure to do so would cut into his profits
* Fakebook would be for everyone, intelligent and not so. The not so's like hysterical racist and other nut job themes, give them what they want, no sense loosing at least half the planet as customers.
* Fakebook may destroy civilization as we know it, but by that time, the mother zucker will have a number of private fully secure and independent islands to live out his life in luxury.
