先前曾傳出 Facebook 會加入 Dislike 功能，但很可能 Dislike 爭議太大了，考量各方面後，Facebook 改成 Reactions 情感符號來呈現，為什麼會這麼說呢？因為 Reactions 的符號裡面就有「難過」這一個，所以後續如果再推 Dislike 那就有點多餘了！話說這系列 Reactions 符號還真的蠻可愛，光是看到就讓人心情開心，可惜的是目前只在愛爾蘭與西班牙開放測試，其餘國家的朋友還需要等等。
Mark Zuckerberg 今日在 Facebook 刊登了一部影片，說明他們在愛爾蘭與西班牙兩個國家開放側的 Reactions 情感符號功能，預設還是原先的 Like 讚功能，但當你長壓時，就會出現其餘 Love、Haha、Yay、Wow、Sad 以及 Angry 情感符號，讓每位用戶都能更完整表達對這則動態的感受。
Today we’re launching a test of Reactions — a more expressive Like button.
The Like button has been a part of Facebook for a long time. Billions of Likes are made every day, and Liking things is a simple way to express yourself.
For many years though, people have asked us to add a “dislike” button. Not every moment is a good moment, and sometimes you just want a way to express empathy. These are important moments where you need the power to share more than ever, and a Like might not be the best way to express yourself.
At a recent Townhall Q&A, I shared with our community that we’ve spent a lot of time thinking about the best way to give you better options for expressing yourself, while keeping the experience simple and respectful. Today we’re starting to test this.
Reactions gives you new ways to express love, awe, humor and sadness. It’s not a dislike button, but it does give you the power to easily express sorrow and empathy — in addition to delight and warmth. You’ll be able to express these reactions by long pressing or hovering over the Like button.
We’re starting to test Reactions in Ireland and Spain and will learn from this before we bring the experience to everyone. We hope you like this – or can better express how you’re feeling!
