YOUR NEWS FEED is about to get a lot more expressive. After months of user testing in a handful of countries, Facebook today is releasing “Reactions” to the rest of the world. The feature isn’t so much a new tool as it is an extension of an existing one; by long-pressing—or, on a computer, hovering—over the “like” button, users can now access five additional animated emoji with which to express themselves. Each emotive icon is named for the reaction it’s meant to convey. “Like” you already know—say hello to “love,” “haha,” “wow,” “sad,” and “angry”.
