Kudos to Facebook! Why Facebook is called as the social network giant? Because they don’t sit and relax and keep focusing on improving user experience.
Recently they have rolled out a pretty straightforward feature called ‘Seen by’ to Groups. Now you will be able to check how many members have seen a post. The ‘Seen by’ feature appears just underneath of each post with a check sign.
Additionally by hovering over the check sign you can see who’s seen the particular post and when. This way anyone who can see the group, can see the post’s ‘seen by’ activity.
The feature has been made available to selective groups, but yet to be live globally! To learn more about ‘Seen by’ visit facebook.com/help/?faq=409719555736128
