Rebecca Rosen for The Atlantic on why maps aren't the best interface all of the time:
Think of it this way. In the days before online trip planners and GPS, if you wanted to know how to get from point A to point B, you would look at a map and trace out a route. But these days few people would use a map that way (I still do just because I enjoy the process but I think I'm in the minority). Instead, they would plug in their request and an algorithm would spit out a route for them. The route would appear on the map, but the map is no longer the tool for finding that answer.
In other words, just because the data has latitude and longitude attached to it, which seems like everything these days, you don't need to automatically assume that you should throw it on a map.
