Facebook has been caught testing a new kind of feed on its mainland mobile app, designed to surface relevant posts from people and pages that you haven't befriended or liked. According to Mashable and Wired, some users noticed a new rocket-shaped icon at the bottom of their News Feed. Tapping it displays content from an alternative News Feed.
Labeled Explore, it's focused on posts, articles, photos, videos and other content from people, media organizations and pages you're not following.
Facebook is currently testing this feature with a small subset of users and could pull it any time it wants. We'll be making sure you're among the first to know when, and if the new Explore tab launches to everybody.
