First, social networking platforms are more convenient and intelligent, they have been saving peoples' time. Because social networks have different kinds of functions, and these functions support for sending voice messages, videos, pictures (including face) and text, and they also support many people to chat in a group. People can share their daily life in friendship circle, send pictures or short videos, describe themselves feelings or emotions, other people can give thumb up, or write reviews. So, social networks opened a new way that let people know more about each other, they have changed people's lives. Second, you don't need to pay money to use social networking platforms.
