A long sequence of numbers in the URL of your Facebook profile has one meaning: it represents how many users have registered on the social network before you. Taking this into account, the Business Insider website met on a list the first users to sign up for social networking.
The first registered user is, of course, Mark Zuckerberg, creator of the service. It has the 4 ID in the URL, since the number 0 leads each person to his own home and IDs from 1 to 3 were test pages, used before the service goes live. The first users are, of course, friends of Zuckerberg at Harvard, and soon after the network has expanded to friends of friends, other college and ultimately the world, since the network now approaching 700 million users.
Survey by the Business Insider, only six of the first 50 users are women. The site listed the early adopters and contacted each one to find out how they found your site. See who are the top 10 Facebook users with active profile on the network in the photo gallery tab above.
