What do the little numbers mean? - each story includes the news source and two numbers. The first number (21 in the example, below) is the 'popularity index' of the story. The second number (23 in the example) is the 'click count'; the number of times viewers have clicked on the story.
Popularity charts - you can track the popularity of a story by clicking on the story's permalink page (the small ∞ symbol). For an example of a popularity chart, click here.
