I found a story about the White House visitor logs from www.nicar.org--the EXTRA! EXTRA! link.
The reporter used statistical computer skills to do this reporting because they needed to look at the White House visitor records requests and figure out in what way the visitor logs are incomplete or if they look incomplete in any way contrary to what the Obama administration says about them.
These are necessary computer skills for the story because it is a lot of data from a pretty long time period and would be extremely difficult to go through without the help of a computer.
The story also has a live data feed from whitehouse.gov, and that extra feature is another computer skill that the reporters had to have been aware of to produce this story.
