The numbers out of Facebook are staggeringly large:
- 0ver 40 billion page views in May 2007
- Over 150,000 registrants daily.
- #1 photo sharing app on the web. 2.7 billion photos on site.
Many would point to these and say they are an example of amazing scaling. Instead, another jumped out at me:
- Half user are outside college. That number was zero in Sept. 2006.
Facebook started in 2004 at Harvard. When they got that down, they added three more universities. After over a year, the site expanded to cover 800 schools. Then they added high schools, they went international, and added work networks.
Finally, after they had things down pretty well, and after two years and eight months, Facebook opened up for everyone to join.
It’s not only about server scaling. It’s about idea scaling.
