What is Social Media?
Social media platforms enable users to create, share, and interact with content — text, images, videos, stories — within a social graph of connections. The technology stack is among the most complex in software: news feed algorithms rank billions of posts for billions of users in real-time, messaging systems deliver messages in milliseconds, content moderation AI processes millions of uploads per hour, and recommendation engines decide what goes viral. India is a social media giant — 500M+ social media users, the largest market for Facebook, Instagram, and YouTube. Indian platforms like ShareChat (regional languages), Koo (microblogging), and Josh (short video) have built massive user bases. Understanding social media systems teaches you feed ranking, graph databases, real-time messaging, ML at scale, and trust & safety.
