Chris Cox, Chief Production Officer at Facebook, describes the new 'button'.
As you can see, it’s not a “dislike” button, though we hope it addresses the spirit of this request more broadly. We studied which comments and reactions are most commonly and universally expressed across Facebook, then worked to design an experience around them that was elegant and fun. Starting today Ireland and Spain can start loving, wow-ing, or expressing sympathy to posts on Facebook by hovering or long-pressing the Like button wherever they see it. We’ll use the feedback from this to improve the feature and hope to roll it out to everyone soon.
During this test, Page owners will be able to see Reactions to all of their posts on Page insights. Reactions will have the same impact on ad delivery as Likes do.
