Unless you've gone to a college in the last 10-15 years (and only when the book existed), you may not even know where the name Facebook came from. (In case you want to know, here's a hint .) Facebook, originally known as thefacebook.com, was a service that connected college students to their classmates and to friends in other universities. The concept was based off a tangible book that incoming freshmen were given each year so that they can meet their classmates.
