Because I ... did not. Even now, I’m not 100 percent sure what it is. There’s a website called Bing Maps, okay, yes, but then the app really just wants to tell me about Microsoft Traffic. And now there’s a way to get Bing Maps info in the Microsoft Start app, which has a feature called Commute that is evidently powered by Bing Maps. Microsoft Start, of course, looks remarkably like the Bing app. Which has mapping stuff in it, but isn’t exactly a mapping app.
