Twitter is a social network based on the exchange of short messages of up to 140 characters: tweets.
On Twitter, every user can post his tweets on the network in a public way. Through the "following" other users can decide whether to receive a notification when another user sends a tweet.
In recent years Twitter, due to a precise company policy, is becoming a peer-to-peer and real-time information tool, covering every relevant news that takes shape in the world in a lightning-fast and global way.
