re: #13 klys

The question isn’t necessarily whether it’s EXIF data, it’s how the location information is generated.

Actually, it is. We don’t know what Instagram does with location data, and whether it stores exactly what it is given, and whether the API is returning the same data it received. For reasons of speed and storage space they may be storing something like a geohash and their stored value and/or API response might be a lower accuracy representation of that location.
