Fascinating video from The Wall Street Journal:
A Wall Street Journal investigation found that TikTok only needs
one important piece of information to figure out what you want:
the amount of time you linger over a piece of content. Every
second you hesitate or rewatch, the app is tracking you.
Not surprising it works this way, but creepy nonetheless. Update: I’ve long suspected that Instagram does something similar, with regard to its often uncanny “Hey, I was just looking at pictures of those…” ads.
