The social network wants to ensure that when a user shares a link to a comedy news article everyone who clicks through is in on the joke. A text message followed by a yellow, winking face makes it clear that the message is a joke, or not to be taken seriously. In fact, taking the contents of a shared Onion article as literal is so common that theres a website, called Literally Unbelievable, dedicated to capturing misinformed comments to misunderstood articles across Facebook. To help users avoid making an appearance on Literally Unbelievable, Facebook is currently testing a ‘satire tag because we received feedback that people wanted a clearer way to distinguish satirical articles from others, a spokesperson told Ars Technica.
