I get a kick out of pinpointing the exact location of photos or paintings. A couple of communities exists for this:
* Geoguessr (I don't participate in this one much, street view is pretty limiting)
* The Dish's "View from My Window" archive. A now defunct blog series where readers would submit photos from their window. Very difficult. Users often pinpoint the exact window from which the photo was taken.

* SkyScraperCity's Guess the City contest. A daily contest to guess the city. Also this is a precious internet 2.0 forum.

* North Korea enthusiasts pinpointing the exact location of Kim Jung Un in official DPRK photos.
* r/whereisthis helps Reddit users locate photos, also allows content just for fun.
* r/PictureGame a more open contest, not necessarily a geolocation task.
