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 c... See more
Today, it’s not as easy to build the “tool” part when so much of that landscape has already been mined and when scaled networks have learned to copy any tool achieving any level of traction.
TikTok doesn’t bump into the negative network effects of using a social graph at scale because it doesn't really have one. It is more of a pure interest graph, one derived from its short video content, and the beauty is its algorithm is so efficient that its interest graph can be assembled without imposing much of a burden on the user at all. It is... See more
Consider Twitter's content moderation problems. How much of that results from throwing liberals and conservatives together in a timeline together? Twitter employees speak often about wanting to improve public discourse, but they’d be much better off (and society, too) keeping the Slytherins and Gryffindors apart until they have some real substantiv...

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?
TikTok is less a pure social network, the type focused on social capital, than an entertainment network. I don’t socialize with people on TikTok, I barely know any of them. It consists of a network of people connected to each other, but they are connected for a distinct reason, for creators to reach viewers with their short videos.
Shopping? A slam dunk, Douyin and Toutiao already enable a ton of commerce in China. Job marketplace? A bit of a stretch, but not impossible. If Microsoft buys TikTok, I’d certainly give the TikTok team a crack at improving my LinkedIn feed, which, to be clear, is horrifying. What about personalized reading, from books to newsletters to blogs? Musi... See more
But what if there was a way to build an interest graph for you without you having to follow anyone? What if you could skip the long and painstaking intermediate step of assembling a social graph and just jump directly to the interest graph?
More than any other feed algorithm I can recall, Bytedance’s short video algorithm fulfilled these two requirements. It is a rapid, hyper-efficient matchmaker. Merely by watching some videos, and without having to follow or friend anyone, you can quickly train TikTok on what you like. In the two sided entertainment network that is TikTok, the algor...
