What I love sharing most on Google Maps is small local business. A number of these business cannot afford a proper social media publicity budget. Most of them are not even aware that they can increase their visibility by posting pictures of their business place on a free service like Google Maps.
Knowing that people are constantly running search queries on Google, looking for the closest supermarket, eatery or car wash, I take it upon myself to add these business places along with their GPS locations to the Map for free.
The businesses get the much needed visibility, I get the credit for it and Google Maps becomes a better search companion. Everyone wins.
