"Each living story resides at a permanent URL, making it easier to follow the latest updates to the stories that interest you, as well as review deeper background materials that are relevant for a story's context. Living Stories automatically track your interaction with the story, making sure that you are always presented with the news you need, the way you want it. You can read full articles and browse multimedia without ever leaving the Living Story page. Just expand the content you want to see, and minimize it when you're done. Whether you want a short update, deep analysis, feature stories, video, or important quotes, everything related to the story is on the Living Story page."
Google Living Stories aggregates a lot of useful information, but some people might find it overwhelming.
