Hey,
I love sharing mostly everything on Google Maps, I shared about local restaurants, local business, local hotels, local cafe’s, events and travel points.
When I am travelling or going about my routine work, I think how I can contribute to others and I put those relevant information, pictures, reviews on Google Maps.
The reason I post all above on Google Maps, is I use Google Map a lot and get benefit of information shared by other users, hence I feel by reviews, pictures may also help others.
