Get your spool-of-yarn emojis ready — threads might be coming to Facebook soon. Facebook has been spotted testing a new feature that gives public figures on Facebook the ability to create a new post that’s connected to a previous one on a related subject. This feature ties the posts together more visually so fans can more easily follow updates over time. When the new post appears on followers’ News Feeds, it will be shown as being connected to the other posts in a thread.
