Facebook launched its new 'Like' button to give an opportunity to the users to express in a more number of ways. These buttons, an extension of Like button, appears on desktop when users hover over the 'Like' button. The reactions include Love, Haha, Wow, Sad and Angry.
Facebook CEO Mark Zuckerberg's Post on Facebook's New Like Button equipped with Reactions:
Today is our worldwide launch of Reactions -- the new Like button with more ways to express yourself.
Not every moment you want to share is happy. Sometimes you want to share something sad or frustrating. Our community has been asking for a dislike button for years, but not because people want to tell friends they don't like their posts. People wanted to express empathy and make it comfortable to share a wider range of emotions.
I've spent a lot of time thinking about the right way to do this with our team. One of my goals was to make it as simple as pressing and holding the Like button.
The result is Reactions, which allow you to express love, laughter, surprise, sadness or anger.
Love is the most popular reaction so far, which feels about right to me!
