This interesting Herald Tribune story deciphers the tangled history of Facebook. Mark Zuckerberg is considered the founder of Facebook, but several others may have claim to the code also. Apparently Aaron Greenspan says he created the original college social networking system and still has the e-mails to prove that claim.
“‘If Zuckerberg did borrow some of Greenspan’s concepts, he may simply have been working in a grand Harvard tradition. After all, it was a young Harvard dropout, William Gates, and his classmate Paul Allen, who almost three decades earlier copied a version of the Basic programming language, designed by two Dartmouth college professors, to jump-start the company that would become Microsoft.”
