Update: Facebook emotions are available worldwide.
Mark Zuckerberg, CEO of Facebook, hinted that facebook was planning on enhancing its like button. Lots of people thought Facebook was going to introduce a dislike button but that was not the case here. They expanded the like button, which now includes reaction emotions. Along with standard thumbs up, there will be some other emoticons for showing feelings for a post. People will be able to respond with Like, Love, Haha, Yay, Wow, Sad and Angry instead of typing their feelings in the comments.
