This document summarizes key points from the book "Gatewatching and News Curation: Journalism, Social Media, and the Public Sphere" by Axel Bruns. It discusses how social media has disrupted journalism by allowing the public to directly participate in the news process through acts of citizen journalism, gatewatching, and news sharing. While this has shifted the balance of power away from traditional media, it has also created new opportunities for journalists and news organizations to engage with audiences on social platforms. However, the rise of audience metrics and platform dominance poses challenges around funding models and potential filter bubbles.
