TechCrunch reports that it takes the form of a new box that sits in the News Feed that lets users swipe between various topics, including Theater, Horror Movies or Photography. Each theme has its own landing page, which details how many sources contribute to each topic and offers an option to connect with them all with a press of a button. Once followed, new posts from those sources will then appear in the main feed.

"We're testing ways for people to subscribe directly to topics in News Feed so they can see more stories about topics they like," a Facebook spokesperson told TechCrunch. "In addition to following specific Pages, this is a new way to follow the general topics you're interested in."

Right now, topics are very light and general in nature, but if the tool proves to be popular, Facebook may decide to expand its reach into more divisive topics like politics. Because each theme pulls from a number of varying sources, followers may be more inclined to read alternative views and question the reporting of their more trusted sources.

Facebook's influence over news cannot be underestimated. In the UK, Conservative MP and the chairman of the culture, media and sport select committee Damian Collins has warned that misleading information on social media could threaten democracy in Britain. "The risk is what happened in America," he said. "The top 20 fake news stories in the last three months of the election were shared more than the top 20 most shared stories that were true."
