The global rollout for Facebook's long-awaited reaction buttons on the social network starts today. So now, instead of just liking a friend's post, you can now react with "love", "haha", "wow", "sad" or "angry" emoji. The new reaction array comes after a year of testing in Ireland and Spain. It's also available for both personal Facebook profiles and Facebook Pages. Despite some early rumours, however, there's still no "dislike" button. There's also no "yay" button even though Facebook tested it, and it's undeniably the best reaction to anything. No yay for you.
