Twitter could soon release emoji reactions for tweets, much like what Facebook and LinkedIn have for their posts. The reactions could include Likes, Cheer, Hmm, Sad, and Haha. These emojis were spotted by reverse engineering excerpt Jane Manchun Wong on Twitter. "We're always exploring additional ways for people to express themselves in conversations happening on Twitter. We'll keep you posted," Twitter said in an email to Gadgets 360 about the new reactions.
