Social media are an important space for people to discuss novel policy innovations. In particular, Twitter, whose user base is skewed toward those who disproportionately affect news coverage, and by extension the public agenda, represents a particularly useful platform for policy advocates wishing to grow their audience. This article extends theoretical understandings of information flows and the growth of networked discussion spaces by examining the online discussion space around a Universal Basic Income (UBI), which has been proposed to alleviate social tensions relating to joblessness resulting from technological advances. Using content analysis and statistical methods, we show that tweets in the UBI discussion space that inform others are the most likely to be shared, but tweets that emotionally resonate with users are the most likely to reach new audiences and therefore bring new actors into the discussion space. These findings contribute to the literature on viral events and dynamic networks, providing insight into how policies like UBI are discussed and diffuse on social media platforms like Twitter.

引起共鸣的推文：信息流和Twitter通用基本收入讨论空间的增长

社交媒体是人们讨论新颖的政策创新的重要空间。特别是，Twitter的用户群偏向那些对新闻报道影响不成比例的人群，并且通过扩展公共议程，它为希望增加受众的政策倡导者提供了一个特别有用的平台。本文通过研究围绕通用基本收入（UBI）的在线讨论空间，扩展了对信息流和网络讨论空间增长的理论理解，提出该建议是为了缓解与技术进步有关的失业相关的社会紧张局势。通过使用内容分析和统计方法，我们发现UBI讨论空间中可以告知他人的推文最有可能被共享，但是在用户中引起情感共鸣的推文最有可能吸引新受众，因此将新演员带入讨论空间。这些发现为有关病毒事件和动态网络的文献做出了贡献，提供了对如何在Twitter等社交媒体平台上讨论和传播UBI等政策的见解。
