I have to say, i love Google Maps, because individual can change the reality of things very quickly. If anything changes, we can instantly say, that there was a change. It´s not the best for navigation by car - Waze is still better. For me, just because there is no speedometer.
If you want somewhere to go, you can see how many people is there in which time, photos, reviews. It´s very usable data for all people around the world…
When I visit a great place, I want to write it down and take a photo of it. Impact is great and very useful. If there is a rude owner, i have to say it to the world, to be careful about it.
