Emoji 'reactions' account for 3% of Facebook Likes

"Back in February, after months of testing, research and quibbling about the design, Facebook excitedly launched the suite of five emoji reactions, from happy to sad, that lets people express their emotions on a post. Turns out, people aren’t using them.
Marketing firm Quintly analyzed 130,000 posts and found that 97 percent of the interactions on them included the use of like button, writing a comment or a share. That means just a measly 3 percent of the time people used a reaction option. The firm concludes that Reactions “are not used very frequently by the average user at this point.”"
