Facebook recently introduced a friends tab to try to recreate the feeling of scrolling your News Feed circa 2006. Alison says they think “there are some features from the very early days of Facebook and social networking that could become more interesting again” as apps including Facebook move toward public, algorithmically-recommended content. He describes it as an “experiment or a bet that we’re making to almost bring a little bit of nostalgia to Facebook as the core experience goes away from friends.”
