It's useless, for me is enough Like/Dislike , Up/Down , White/Black, Green/Red, bla bla bla ... I Know some forums who install such of addons and after 2 months they disable it beacause of huge load on mysql server, and the reason was this emoticons/reactions. If you want to add this in next version 7.4 think how you will cache them beacuse people will start to use them more beacause is much easy to press a button instead to comment an article, and this is another reason why this forums disable them see more because they decreased in comments in favor of reactions.
