The 10 most popular articles of 2009.

Whenever Slate chronicles its most-read stories of the year, the list is revealing. Some years, readers are interested in beer, babes, and puppy dogs. In 2008, they were hungry for news of the election and the economy. In 2009, readers wanted a bit of both. Stories about the Obamas—what Barack was reading, how the family moved into the White House, what the president's Secret Service agents look like—were very popular. And readers flocked to slide shows about the recession, including one on Detroit and one that gathered Slate readers' photos of the economic crisis. But more unorthodox stories also found traction. June Thomas' series on the crisis in American dentistry was widely read, as was a slide show on strange maps, our Mad Men TV Club and—our most-read story of the year—a taste test of chain coffee. Below, you'll find a list of the 10 articles and five slide shows that attracted the most readers this year.
