So neither the instapaper blog post (linked here) nor the news.me blog post (http://blog.news.me/post/21643399885/introducing-paper-boy-a...) comes right out and says it, but the point here is that since iOS doesn't let an arbitrary program schedule itself in the background or on a time-based schedule, but the iOS geofence APIs do let an arbitrary program schedule itself when you cross a geofence, you can abuse the latter to simulate the former?
