Prior research on YouTube has examined “maker culture” and DIY tutorials (Knobel & Lankshear, 2010). However, Bilibili differs crucially: its danmu (bullet-screen) system allows real-time, time-stamped comments that overlay the video, creating a collective viewing experience. Wang & Gu (2020) argue that danmu fosters “co-learning” where viewers correct, praise, or joke alongside the instructor.
