A "Gatekeeper" is a person or entity that controls access to something, such as information, resources, or opportunities. In various contexts, gatekeepers can be found in businesses, where they manage who can speak to decision-makers, or in healthcare, where they determine patient access to specialists. Their role is crucial in filtering and prioritizing requests. In the digital world, gatekeepers often refer to platforms like Google or Facebook, which regulate what content users see. These companies influence the flow of information and can impact public opinion by deciding which voices are amplified or silenced. Their power raises questions about fairness and transparency.
