I love sharing the reviews, photos, videos, adding missing places, updating information. I share my contribution to google maps and so does other google local guide. This process makes an honest exchange of information and helps me to see the honest reviews, photos, videos of places that I am planning to visit. For example, I was on holidays last week to Naples, Italy. In google maps, I searched for pizzeria and found one pizza restaurant with over 11000 reviews and 4+ rating. This makes undoubtably a must-go restaurant when visiting there. This value addition in google maps compliments its very purpose. It saves time and money to buy guide books, searching not-so-trustworthy-as-google websites for best pizza restaurants.
