In the article "Mild, dry winter delights some, depresses others" by USA Today the authors use people as their sources.
Going though the article, I counted a total of 9 people quoted or paraphrased. A lot of that is because the story has a number of personal accounts of how the unusual winter has affected them.
All of the sources are spread throughout the article but it doesn't get to confusing because the authors usually introduce a person for a quick quote or information and then don't bring them up again.
The Weather Channel meteorologist Frank Giannasca was the only individual brought up later after he had initially been introduced.
I think the multiple sources if effective in this case because the article needs a variety of opinions. The point of the story is that the winter is affecting many people in many ways so the authors must then follow up that claim with the evidence.
