надо сказать фейсбук выглядит как некая паталогия, но в принципе если почитать про основателя, то вполне паталогии видны:
According to Zuckerberg's roommate at the time, Arie Hasit, "he built the site for fun." Hasit explains:
We had books called Face Books, which included the names and pictures of everyone who lived in the student dorms. At first, he built a site and placed two pictures, or pictures of two males and two females. Visitors to the site had to choose who was "hotter" and according to the votes there would be a ranking.
