Do you have the Rocket Icon on your Facebook mobile app toolbar? Mine, just appeared yesterday. Facebook is testing a mobile only second news feed. The Rocket News Feed are suggestions of content based location, your interest, and likes. Because I used my personal feed to research for work, my content suggestion has a wide range of content (see below).
Because this feature is still in the testing mode, not all people will have it. According to Facebook, “We are testing a complementary feed of popular articles, videos, and photos, customized for each person based on content that might be interesting to them. We’ve heard from people that they want an easy way to explore new content they haven’t connected with yet.” If the test group likes the Rocket feature, Facebook will “launch” it to everyone’s mobile feeds soon.
