When I started using google maps as a user who just wanted some information, I realized that I found 5 stars rating in places I would rate with 1.
Some stores were placed 50 meters far from the right spot.
There was many entries for one place and many places with no entry.
Some very bad blury photos were the only way to see the food of the restaurant that I wanted to visit.
Facing all these problems, I decided to participate and help to make it work better. The fact that I like photography contributes to take some photos for places that not have any; and the fact that I like having all the information I want, makes me giving any information in advance, so every people with the same needs as me can find what they want.
I am on my first steps and I am sure that I can do better.
All we have to do is to leave our honest opinion with no malice, and leave some useful information for those who need it.
