Or you could do one that takes data like clicks on new stories, and uses it to promote old stuff. For example, take political news: if there's a news story about a politician's sex scandal, older content that mentions the politician and sex scandals could get a bump; if there's a story about a politician demanding a tax cut, older stories about the politician's attitude towards taxes could be promoted, instead.
