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 become a tertiary space for news that does not privilege journalists, how metrics can promote populism, and how gatewatching and sharing news is now habitual. It also notes opportunities for journalists as curators and personal brands, and how generational shifts are increasing reliance on social media as a primary news source while platforms siphon advertising revenue.
