In case you hadn't seen or weren't aware, the Arthur L. Carter Journalism Institute at New York University has a list of the 80 best works of journalism in the U.S. this decade. They are the nominees that will be culled to a top 10.
There are print stories, books, radio stories, visual stories, and so on. Click on the title and it gives you a description and a link. It's really interesting, especially to go back and see what you may have missed -- like a "60 Minutes" report in 2000 about Pakistan's instability and Islamic militants that ended up being "prophetic," in the judge's words, when applied to Afghanistan.
