The notion i am going to talk about is places and exchanges.
I will present this notion by showing what influence the web has on today’s society.
Let's take the case of the social networks.
A social network is a tool where we can exchange informations.
The most famous are Facebook, Twitter and Snapchat.
But Google Maps can be also considered like a social network because you can exchange informations about a destination or a new itinerary.
Despite all of this, this tool is very interesting because if we are lost we can find our way or find a new itinerary.
Moreover with social networks we can create rally.
The most famous is the flash mob.
The flash mob is organised by a classical art foundation, and the instructions are given on a web site
But these events organized on social netwoks can take negative points.
A good exemple is the flash mod who will be changed in flash looting.
So technologies can bring negative effects on some people.
And social network can empowered the mod
In addition even if Google Maps is a very interesting tool, it can be a tool for the robbers and robberies can be easier.
To sum up the main ideas we can conclude, socials networks are used by billion users every days. So they influence the people but they aren’t always good for us
