   Short-form video sharing mobile applications like TikTok (Douyin) have been gaining traction globally in recent years. These video sharing platforms have transformed how users consume online content in a drastic way. The recommendation algorithms of these applications form a ``ludic loop'' for users -- the more users watch videos, the better the algorithms work, and the more users are exposed to content of their interest. Although prior research has explored how and why users watch short-form videos, relatively little research has studied those who choose not to use Douyin. To address this, we conducted a survey study with Internet users in China (N = 192), focusing specifically on Douyin and those who have abandoned or never adopted Douyin. Our results show that various perceptions of these users shape diverse practices of engagement with and disengagement from Douyin. Those who choose not to use Douyin are mostly motivated by the fear of addiction, or the stigmatized perceptions of videos on Douyin that deemed low-quality. Those who are using Douyin and those who choose to quit Douyin have different perceptions of the efficacy of Douyin's recommendation algorithms. We situate our findings with prior research on technology non-use, and provide design implications for future video-based social media.

   Despite gaining traction in North America, live streaming has not reached the popularity it has in China, where live- streaming has a tremendous impact on the social behaviors of users. To better understand this socio-technological phenomenon, we conducted a mixed methods study of live streaming practices in China. We present the results of an online survey of 527 live streaming users, focusing on their broadcasting or viewing practices and the experiences they find most engaging. We also interviewed 14 active users to explore their motivations and experiences. Our data revealed the different categories of content that was broadcasted and how varying aspects of this content engaged viewers. We also gained insight into the role reward systems and fan group-chat play in engaging users, while also finding evidence that both viewers and streamers desire deeper channels and mechanisms for interaction in addition to the commenting, gifting, and fan groups that are available today.

   The {\$}5 billion dollar live streaming industry has a tremendous impact on the social behaviours of internet users in China. However, despite early appearance of the technology in the North America, live streaming has yet to reach the level it has in China. Using observations from the rise and proliferation of live streaming services in China, we identify some culture and social insights about the phenomenon as well as some lessons that we can apply to North America.
