That is insane. I don't know of any other platform (except for maybe image heavy subreddits?) that have that rate of content consumption. Facebook obviously tries, but they are so focused on their limited content sources that they frequently don't have the content people want. Twitter has similar issues, if there aren't 50 tweets you want to read in a row, as you keep scrolling Twitter has to drop the quality of content down to make sure the feed shows something.
But by being willing to surface any type of content (give users what they want), it sounds like Toutiao has been able to fully leverage AI, removing constraints on what content exists naturally leads to better results.
Also, it is a miracle if they truly solved ad targeting. In comparison, I am still getting ads for a belt I bought 3 weeks ago.
