The common place articles go with a less formal tone..However, even being less formal, the authors still manages to make a interesting, valid and constructive points with their essays. The article i read,"Lucky there's a family guy" used a lot of rhetorical questions. i find this very successful as these question inspire readers to think while reading the article, but also, it makes it feel like the essay is more conversational, it is as though she is personally asking you a question with a very casual everyday conversation tone. the use of this tone actually encourages readers to actually try to comprehend the text and think of an answer to the question as readers feel like they are in a conversation waiting for a reply.
