Shelley uses youtube social media software to share her views on different topics such as education. She makes a lot of videos on different topics, and her videos cover a very wide range of content. I find her videos very engaging, she throws questions to make us think first and then gives examples that surprise us. For example, she watched bowling games to learn how to hit more bowling balls. When her friend responded, she took into account that more ways to hit the bowling ball also apply to education. This surprised me very much. At the same time, she will share her favorite books, which we can easily buy online. We can choose between paper books and e-books. This is the knowledge sharing that online social media brings to us. We can listen to a lot of PhDs and professors on the Internet and listen to their views on a lot of things. I think this is the greatest convenience that network media brings to people.
