One of the Facebook features some web users are yearning for is the ability to dislike certain posts or photos. It appears that such wish might be granted as Facebook CEO Mark Zuckerberg recently admitted in a Q&A session that he's thinking to add a "dislike" button to enable users to voice out their sentiments further.

Zuckerberg says that the Facebook "dislike" button will not encourage negativity but will allow users to respond properly to "unhappy things like a death in the family or a personal struggle."

He clarified that a Facebook "dislike" button wouldn't be created to bring others down: "You know we're thinking about it, on the Dislike button. It's an interesting question, right, because there are two things that it can mean. Some people have asked for a Dislike button because they want to be able to say 'That thing isn't good'. And that's not something that we think is good for the world. So we're not going to build that. I don't think there needs to be a voting mechanism about whether posts are good or bad."

"You know a lot of times people share things on Facebook that are sad moments in their lives, or are tough cultural or social things and often people tell us that they don't feel comfortable pressing Like because Like isn't the appropriate sentiment," he explained.

"So one of the things that we've had some dialogue about internally and that we've thought about for quite a while is what's the right way to make it so people can easily express a broader range of emotions to empathize or to express surprise or laughter or any of these things," Zuckerberg added.

Apart from revealing the possibility of having a "dislike" button, Zuckerberg likewise addressed the concern of why Facebook users wouldn't be able to have many usernames.

"We limit each person to having just one username so they can be found more easily. The username is less important than the fact that on Facebook, people use their real names. There's more accountability if you're connected to your real name," he said.
