The document discusses Facebook's recent changes to its news feed algorithm. It explains that Facebook made the changes to prioritize personal connections between users over public content from businesses and media. The new algorithm focuses on active interactions like comments and shares rather than passive viewing. It breaks down the algorithm into four components: inventory of available content, signals about the content and person, predictions about the person, and an overall score. The top ranking factors in the new algorithm are active interactions like commenting, sharing, and reacting rather than passive viewing or scrolling.
