Facebook has made a slight change to the way related posts are shown, after a user clicks on a link in News Feed.
Previously, when someone clicked on a link in News Feed, Facebook would show a few stories related to the topic. This used to be done horizontally, but now it appears that Facebook is testing this vertically, taking up more room in the News Feed.
Readers: Have you seen this?
