No judgment: value optimization and the reinvention of reviewing on YouTube
研究YouTube评论视频如何通过内容分析揭示创作者遵循平台激励，用审美、功能、独特性等标准评价产品，并避免强烈判断，形成“价值优化”策略，改变了评论的传统功能。
Abstract Social media platforms employ algorithmic recommendations to optimize the user's experience and incentivize particular forms of cultural production. While prior research shows that creators respond to these incentives and seek to optimize their content in return, the normative implications of this process are ambiguous and contentious. To examine the values promoted by platforms, this study focuses on YouTube reviews, a popular genre that crosses communities and foregrounds values. Employing content and thematic analyses of 200 videos, I find that creators communicate value consistently: good products are aesthetic, functional, distinctive, and either pleasurable or resonant, while good reviewers are relatable above all else. I develop the concept of value optimization to refer to communicative strategies that appeal to the perceived values of a platform and show how creators’ tendency to qualify their evaluations and avoid strong judgments transforms the historical function of reviewing. Finally, I discuss implications for future research on the platformization of cultural production.
