A lot has been said about the ‘social media bubbles’ of the modern online world. For those not familiar, the ‘bubble’ is in reference to the effects of the algorithms that Facebook, Google, and the like use to determine what to show you when you use their sites.
The term usually refers to the political echo chambers that these algorithms create. You watch a video/like a comment/click on a search result with a certain percieved political viewpoint and these sites decide that you must want more of that same viewpoint, since they are ‘similar’.
