Facebook is constantly tinkering with its platform – you may have noticed it recently added Snapchat-style stories at the top.
The latest addition comes in the form of a small rocket icon that has been dropped in next to your friends and notification buttons. Tap on it and it takes you to an alternative news feed – giving you even more content to browse.
The second news feed displays pictures, articles and other posts from sources that you haven’t explicitly followed. But, given what you do like, Facebook thinks you’d still be interested in seeing it. Eventually, the new feature could prove useful in breaking people away from being handed like-minded content.
