On February 19th, 2012, a post on tumblr introduced the airport game. Hiding your location, the game begins with randomizing your location, then finding an airport to "get back home". Led to the majority of tumblr wandering far corners of the Earth for hours, following random trucks. Screenshots were abound on tumblr of random locations combined with the player's declaration of misery. Occasionally someone managed to find the airport. Such people were revered as gods.
Tumblr user: WHO PUT THESE MOUNTAINS HERE?
Person 1: What.
Person 2: Mapcrunch.
Person 1: Still what.
Tumblr user: THE TRUCKS LIE.
The existence of this site lead to the invention of the online MapCrunch Game (also known as "airport game" or "MapCrunch Airport Quest"). To participate in the game, you just go to the site (mapcrunch.com), click "hide location" and press "go", then you start looking for the nearest airport (with as less help as possible), so you can go back home.
The game was invented by the community of Tumblr and caused the website serious server troubles on Feb 19th 2012 because the site hits went up by almost 1500% within 24 hrs.
