Facebook could soon start hiding the Like counter on News Feed posts to protect users’ from envy and dissuade them from self-censorship. Instagram is already testing this in 7 countries including Canada and Brazil, showing a post’s audience just a few names of mutual friends who’ve Liked it instead of the total number. The idea is to prevent users from destructively comparing themselves to others and potentially feeing inadequate if their posts don’t get as many Likes. It could also stop users from deleting posts they think aren’t getting enough Likes or not sharing in the first place.
