Facebook users were introduced Wednesday morning to five new options for interacting with posts, photos, articles and more. In addition to the Like button, Facebook users on both mobile devices and computers can now click the Love, Haha, Wow, Sad, or Angry buttons.

It Took a Year to Pick the Emotions

Facebook spent over a year trying to figure out what buttons should be added to interact with posts, CNN Money reports. The social media company studied the popular emojis used on their site, consulted with sociologists, held focus groups and distributed surveys to decide which emotions would join the generic Like reaction.

The update is a response to site users who wanted more options to interact with posts. A Like is not always appropriate for every post that appears on Facebook, but people still want to interact with what their friends are posting.

Love Emotion Is Popular Already

The new emotions added to Facebook are called Reactions, and they were already available in Spain, Ireland, Chile, the Philippines and a few other countries before being rolled out worldwide on Wednesday. So far, people are reacting positively to the new emotion options. The most popular Reaction so far has been the Love button.

No Dislike Button Yet

Facebook decided not to offer a Dislike button because CEO Mark Zuckerberg thought that it would turn the social network into a site where trending popularity was based on up and down votes. Zuckerberg said he did not want that, despite the fact a Dislike button was among the additions users requested most.

"That doesn't seem like the kind of community that we want to create," Zuckerberg said during a town hall Q&A.

Mixed Reactions on Twitter

Here is what some people are saying about Reactions on Twitter.

One particular insight was offered by Carl Franzen, the online director for Popular Science, who compared the Love button on Facebook to the Like button on Twitter.
