In recent weeks, some users have started noticing a rocket-shaped icon in their Facebook mobile app.
The icon, positioned right next to the main news feed icon, gives you a different type of news feed, one which displays popular posts from people and pages that you haven’t befriended or liked.
The new feature has been on Android for at least three weeks now, though it tends to disappear and reappear every now and then. (I’m based in Croatia, but there are also reports of users seeing the new icon in the UK.)
The rocket feed offers a great deal of local content, so it’s possible that it’s showing posts that are popular near my geographical location. However, I’m also seeing some posts that are relevant to my interests, so it might not be completely disassociated from my likes/friends.
The new feed seems to be remarkably similar to Instagram’s Explore tab, which shows you posts that the company’s algorithms have determined to be relevant to your interests.
