Another interesting thing is LIKE button. Its a very unique thing in Facebook product! People uses this LIKE button on people's post so that other people and the user himself can know how amount of people likes that particular post. But as the time goes on people got bored with that Button. Many of them requested to give a Dislike button with the LIKE button because all the post are not worthy for Like. In many Townhall Q&A of Facebook, CEO Mark Zuckerberg faced the same question that why he don't launch Dislike Button.
LIKE button is not suitable for all posts like if anyone posts sad or ill news then its not the right place to give a like button because you are not going to show other people that you are liking this post besides you are also not going to give a Dislike instead of that because its also not looks good where you need to show Sympathy here. In Facbeook all the users has the right to post something good according to their taste and if anybody Dislikes this it looks mean or rude thats why facebook doesn't want to create a harsh situation. We’ve been listening to people and know that there should be more ways to easily and quickly express how something you see in News Feed makes they feel. That’s why after a huge thinking and working on it today Facebook has launched Reactions, an extension of the Like button, to give you guys more ways to share our reaction to a post in a quick and easy way. From that button there is Love,Laughing,Amazed,Sad and Angry and of course there will be LIKE button also so that people can get a meaningful expression for their posts. So these are the reaction button which is launched in Facebook. All they need is to press the Like button for a few seconds and then they will able to see the 5 new reaction button and click/tap on that icon of reaction.
