Facebook mulls over 'dislike' button

Facebook founder Mark Zuckerberg says his site is "thinking about" how to implement a way to dislike posts on the social network.

Speaking to an audience during a Q&A session in California, he said the feature must not become a way to demean people, but that it would be valuable to show other feelings other than "like".

The Like button, introduced in February 2009, is used up to 4.5 billion times each day.
