Quotes under the Facebook's search box
Mark loved good movies. He had a couple of favorite quotes from films like Top Gun or Troy. To emphasize the boyish, teenage nature of his company, he put some lines from those movies under the search box on his site.
Sometimes it could be something like “Now you know who you're fighting” from Troy, and other times – “Too close for missiles. Switching to guns” from Top Gun.
It turned out that it engaged students. Over time, they started arguing what “the author thought” when putting these lines. In fact, those quotes were put totally without any goal, just like the Poking function. And, just like Poking – they stormed campuses.
Students usually like watching movies, especially those most popular action films. The quotes matched not only TheFacebook's philosophy, but also its users' tastes.
