One thing I like doing in Maps is posting a missing place or making modification to an existing place. This is not only because of the points and such, but also to make things a lot easier on Maps.
When a place is there in Maps, it’s so easy to travel. If you have a doubt, look at your phone and understand where you need to head.
When adding/modifying a place, another person could just search for it and be glad that they know which way to take and what to expect from the place. Also, the owner of the place could get more customers now that his/her place is in Maps. The owner may not know much about Google Maps (which is mostly the case in my community, I think). So, doing this could do big things to the business and also to the customers.
