RedNote, also known as Xiaohongshu, rockets to top of US app stores, along with ByteDance’s Lemon8

New users have piled in to the Chinese social media app RedNote just days before a proposed US ban on the popular social media app TikTok, as the lesser-known company rushes to capitalize on the sudden influx while walking a delicate line of moderating English-language content.

In a live chat dubbed “TikTok Refugees” on RedNote on Monday, more than 50,000 US and Chinese users joined the room. Veteran Chinese users, with some sense of bewilderment, welcomed their American counterparts and swapped notes with them on topics such as food and youth unemployment. Occasionally, however, the Americans veered into riskier territory.
