Update :
After almost a year, I got an email back from Follow Your World which notified me that above marked place was changed. Totally awesome. You can see in the image below, how Follow Your World spotted a difference when it saw change in colours. This happened because of recent renovation at the stadium.
You also get a Dashboard which lists down all the places you are tracking with details on when you where notified last, Status one click to unsubscribe from it. The only drawback is there is no way to edit once you have submitted it. So if you want to change, unsubscribe and create new point.
