I was born in 2004 from the mind of Harvard student Mark Zuckerberg. Initially, I was simply a toy for Harvard students, but I quickly caught on with the co-eds at Yale and Stanford, too. In the blink of an eye, high school and college kids around the world were networking with me. Now, I've ditched the student-only restrictions and I'm interfacing with all kinds of people from around the globe, helping them keep up with family, friends and meet new people.
