Online Trick

When Facebook was founded, every user was given an ID number. It began with ID #0, which redirects every user to their own profile page. ID numbers 1-3 were tests that Mark Zuckerberg used to initially test Facebook; the profile pages no longer exist. The first real Facebook user starts at ID #4. It belongs to Mark Zuckerberg. Facebook ID numbers were assigned in somewhat sequential order; schools were chunked up in blocks up to 100,000 IDs. Harvard was the first chunk (0-99,999). My number is about 5,500,000. This makes sense because Syracuse was the 56th school on Facebook. It's not clear how IDs were assigned once Facebook expanded beyond college networks. But, if you were an early Facebook member and joined through a university network, your ID number probably closely resembles the order in which you signed up for the site.
