Facebook用戶以往對其他用戶的文帖和照片作出回應時，只可以選擇文字回應和按「Like」（讚好）；可是，fb近日推出新功能Reactions（反應），供全球用戶，包括香港在內的多個國家和地區，使用表情符號按鈕作出回應。
現在，用戶除了按「Like」外，亦可以留下「love」（勁正）、「haha」（哈哈）、sad（慘慘）、angry（嬲嬲）及wow（嘩」）5種動態反應。
網頁版的fb用戶只需要把滑鼠移到「like」鍵上，便會彈出5個新表情符號；而iOS或Android版的fb用戶則需要長按「like」，才可顯示出來。跟以往一樣的是，倘若不小心按錯，是可以取消和重選；而原本計算like數的位置上，則會顯示3項最多人按的反應，只要用戶點擊進去，便可以查看統計資料。
Fb始創人Mark Zuckerberg(朱克伯格)在星期三就新功能發表聲明，表示明白我們的生活中，並非每一個時刻都可透過「讚好」來表達心情，所以加入不同的表情符號，其中以「勁正」最為受歡迎。
Mark Zuckerberg文帖全文：
Today is our worldwide launch of Reactions -- the new Like button with more ways to express yourself.
Not every moment you want to share is happy. Sometimes you want to share something sad or frustrating. Our community has been asking for a dislike button for years, but not because people want to tell friends they don't like their posts. People wanted to express empathy and make it comfortable to share a wider range of emotions.
I've spent a lot of time thinking about the right way to do this with our team. One of my goals was to make it as simple as pressing and holding the Like button.
The result is Reactions, which allow you to express love, laughter, surprise, sadness or anger.
Love is the most popular reaction so far, which feels about right to me!
