Isn't a social network, it is a place network. Now you can know who was there before you, the person isn't the most important because you want to know everything about the places not about the users.
When you go to a plaza, a museum or to the beach, you are between a lot of people but you only want to see the place and everything around you.
Is time to see what you really want to see, no what your friends/following wants to show you.
In the real life you do not walk all day and everywhere surrounded by your friends. you go to places where there are many strangers where you dont wait see friends, where if you meet a friend is awsome.
