Facebook is testing a “dislike” button for the first time, in response to high demand from users. The feature has been rolled out to a small number of people on the Messenger app, who now have the option to respond to individual messages. Facebook wants users to attach emojis to messages in a similar way to the “reactions” feature on the news feed.

From my point of view, the “dislike” button will be popular among users. With the “Like” and “Dislike”, users can better express their opinions. #StayTechie https://christopherewhite.wordpress.com/
