Click-bait articles are rife online. Countless websites ply a trade in leading headlines designed to lure readers in, giving as little away as possible as an encouragement to click through. A virtual prick-tease, if you will. Sometimes the click is worth it, but all too often the article, particularly on tabloid-style newspapers, magazine websites and sites peddling listicles, is pointless or misleading. A suggestive question, the promise of sex, inappropriate references to the iPhone 6, the implication of free money… the possibilities for click-bait are virtually endless. It, understandably, annoys a lot of people, and it has annoyed Facebook enough for the social network to take a stand.
