I find it hard to believe that this has to do with the superiority of TikTok's ranking algorithm, and everything to do with the fact that its more popular with younger people.
On the content side, they must have some kind of digital crack making young women want to post thirst traps and live feeds. I don't know what combination of attention and gifts makes a person do that, but Facebook sure doesn't have it.
Is a "thirst trap" some kind of innovation specific to Tik Tok? How are they inducing their providers to post this innovatively addictive type of content?
