The brains at Instagram launched what they thought was a limited experiment in horizontal scrolling of posts Thursday but it got out of hand. The unannounced refresh, which Instagram has since labeled as a bug, took users by surprise. Instead of scrolling through posts vertically, some people were forced to swipe and tap left and right through their feeds, similar to how the app’s stories feature works. Users went berserk on social media, with #instagramupdate trending on Twitter. Instagram quickly reverted back to the original top-to-bottom scrolling feature even before everyone had seen the update. All just part of the heavy burden of being manipulated by geniuses running your social media life.
