The latest addition to Facebook's never-ending parade of experimental features looks like it's all about fake news. Chris Krewson, an editor for Philadelphia publication Billy Penn, has spotted a survey module right underneath a post by the Philadelphia Inquirer about a white nationalist (and well-known pistachio vendor) losing her job. The survey asked: "To what extent do you think that this link's title uses misleading language?" There were five choices to choose from ("Not at all," "Slightly," "Somewhat," "Very much" and "Completely"), but the module could clearly be dismissed with by clicking on an "X" button.
