TikTok and the Sorting Hat - TikTok's algorithm is so good at organizing users into subcultures that it was able to skip the awkward early phases of new social media

    From the article:

    They say you learn the most from failure, and in the same way I learn the most about my mental models from the exceptions. How did an app designed by two guys in Shanghai managed to run circles around U.S. video apps from YouTube to Facebook to Instagram to Snapchat, becoming the most fertile source for meme origination, mutation, and dissemination in a culture so different from the one in which it was built?

    The answer, I believe, has significant implications for the future of cross-border tech competition, as well as for understanding how product developers achieve product-market-fit. The rise of TikTok updated my thinking. It turns out that in some categories, a machine learning algorithm significantly responsive and accurate can pierce the veil of cultural ignorance. Today, sometimes culture can be abstracted.

    Before Bytedance bought Musical.ly and rebranded it TikTok, its Musical.ly clone called Douyin was already a sensation in the Chinese market thanks in large part to its effective algorithm. A few years ago, on a visit to Beijing, I caught up with a bunch of former colleagues from Hulu Beijing, and all of them showed me their Douyin feeds. They described the app as frighteningly addictive and the algorithm as eerily perceptive. More than one of them said they had to delete the app off their phone for months at a time because they were losing an hour or two every night just lying in bed watching videos.

    It’s rumored that Bytedance examines more features of videos than other companies. If you like a video featuring video game captures, that is noted. If you like videos featuring puppies, that is noted. Every Douyin feed I examined was distinctive. My friends all noted that after spending only a short amount of time in the app, it had locked onto their palate.

    That, more than anything else, was the critical upgrade Bytedance applied to Musical.ly to turn it into TikTok. Friends at Bytedance claimed, with some pride, that after they plugged Musical.ly, now TikTok, into Bytedance’s back-end algorithm, they doubled the time spent in the app. I was skeptical until I asked some friends who had some data on the before and after. The step change in the graph was anything but subtle.
