Design question: Why do authors take nice sounding quotes from the text and put them in large text aside the article? Is it to keep people interested, as in the reader is thinking "This article is awful" and then they see an amazing quote farther down the page and decide to keep reading? Maybe the writers at nytimes have a picture quota and putting pictures of lines from the article technically counts? Maybe WE as readers require pictures to stay interested, and these large quotes somehow satisfy that need? I just get tired of reading the same lines twice.
