It’s very simple, I believe that if you help others God will help you, and sharing photos, information, giving feedback is a great way to help others. I too have experienced the problem of searching new location on Google Maps and when you don’t get any details about the local place it’ hectic. Whenever I visit somewhere Google asks me to review that place, and I actively post the photos(if any) and the general information, because you never know may be that information would be so so so important for the person.
