Have +any+ social media platforms managed to recruit new generations of users, after the first generation? It seems that each new generation starts its own new community, rather than joining an existing platform.

Perhaps YouTube is an exception if we call that a social media platform (but maybe Tik Tok is replacing it)? Are there any others?

@owen Facebook acquired an older generation. But you probably mean has any social media managed to be adopted by the generation coming after its first user base. To which I say: good question!
