Yep exactly. I’d argue they create echo chambers far more than we’d like to admit. It’s also not simply voting but also algorithmic of sorting content by likes, and implicitly excluding anything under a certain threshold. I’ve felt this way for nearly twenty years now, coinciding with the rise of reddit, twitter, and facebook alongside the decline of forums, blogs, and rss. On any topic with even slight amount of contention, you very quickly see people aligning toward the one-true-belief because they observe and react to the crowd supporting that opinion.
