I find TikTok and Instagram primarily about vanity, show-boating and moral crusades than creative expression. Of course, the internet of old had those negative elements in it, but now those seem to have become the bread and butter of such networks.
Dig deeper. TikTok is fantastically weird and niche. I've learned about so many things I'd never seen on the web or YouTube like small scale trains that people ride around in their back yard, throw gliders, and tether car racing.
