Why do the same few voices always dominate every social media platform?

Researchers analyzed millions of user interactions across multiple social media platforms and found that inequality in who gets heard is remarkably consistent: the same tiny elite captures most posts, likes, and comments, whether you measure it on Twitter or Reddit, and this imbalance doesn't fade over time. The uniformity across platforms with vastly different rules and audiences suggests this isn't a bug but a feature of how online visibility works.
