Coming soon to Facebook: a button that lets you express emotions beyond the iconic thumbs up.<br />Founder and chief executive Mark Zuckerberg made the announcement Tuesday during a Q&A session streamed live online from Facebook headquarters in Menlo Park, Calif.<br />Facebook has resisted creating a "dislike" button as a companion to its "like" button, fearing it would sow seeds of discontent on the world's most popular social network.<br />But in recent years Zuckerberg softened his stance, responding to popular demand from Facebook users who say "like" does not fit certain status updates and situations, say a death in the family or a crisis.<br />"While many users love the idea of Facebook adding a dislike button, I don't think there are many users who are dying to have their own content disliked," the engineer wrote.
