Startup Idea : App to Notify you about interesting places nearby

App is running in the background and checks your location from time to time (once an hour). It will search for interesting places in online databases (like Wikipedia) and notify you if you are currently nearby. This way you don't miss something interesting when walking or driving past it. I've checked - Wikipedia allow to search for articles by location. It has a lot of content already. No need for UGC and moderation. The app can be self sustainable. Feedback?
