Null Island: The most populated place that doesn't exist

This is a very interesting video about a place that doesn't really exist called Null Island. But when I say it doesn't exist, I don't mean that it's necessarily fictional. It does exist, mostly in the form of a digital footprint.

Null Island is the coordinates for 0,0 (Latitude, Longitude) which puts you smack dab in the middle of the South Atlantic Ocean (not too far off the Western Coast of Africa). The reason why this place exists is when GPS can't find your location immediately, it substitutes your place as 0,0, which translates to "null" in a program -- hence Null Island. So sometimes, there are photos tagged here even though nobody in their right mind would ever vacation to an ocean buoy. NOW YOU KNOW!
