>The stable community is driven in part by their algorithms, which replace Instagram and Facebook's idea of a feed of those you follow. It gives more power to TikTok, in that you won't notice if some members of the community leave, and they can continue showing you content you'll enjoy from millions of other users.

The endurance of Facebook, Instagram, Youtube and Twitter is the precisely because of the connect/subscribe/follow model.

Algorithmic content from random creators is not a model for creating an enduring user base. Users will eventually get desensitised to it and leave. There's a limit to how many memes you can consume.
