This time it’s about Sarah’s blog about why social media is growing so fast. Her blog has a black background and rich pictures, which can effectively attract an audience, which she does very well. Her first paragraph gets right to the point and cites computers and televisions as examples of how they have changed. Meanwhile, she points to social platforms Instagram and Facebook as examples. Compared with the previous era when social platforms were not popular, young people are the main beneficiaries. With the development of social media, social media is more and more convenient for people’s lives. Today’s social media is a skill that young people must learn. Some older people are also learning new social media, even though they still prefer traditional media. She also uses radio as an example, which is the basis for the emergence of social media. All kinds of inventions are good for people to convey information. They meet the needs of the public and are naturally easier for everyone to accept.
The dependence of social media on people’s needs is the central idea of this article and the ideas to be expressed.
Today, there is a tremendous variety of social networking sites, and many of them can be linked to allow cross-posting. This creates an environment where users can reach the maximum number of people without sacrificing the intimacy of person-to-person communication. （ Hendricks D，2013 ）The environment created by social media has more people and space, and has more private space to ensure the safety of chat content.
The main idea of the article is good, but it lacks her own ideas and opinions. I hope she can add more of her own suggestions and opinions, which will enhance her interaction with the audience.
