The Internet has changed the very idea of interaction between teachers and students.
If in the past interaction between teachers and students was formal, nowadays the Internet and social networks have changed the very idea of interaction between them. On the Internet students and teachers are becoming virtual “friends”. Interaction between teachers and students on the Internet has become informal. On the Internet students may speak with their teachers informally, instead of using the formal language they use to a teacher in real life.
Social networks allow their users to look through the private information, photos, personal content on free access. As a result, students may receive an information about their teacher which would never be shared in a classroom setting. So I think that Internet is not the best way of making friends with your teacher.
