I wasn't comparing the creator threshold with TikTok; that's a much bigger leap for me too (though it probably wouldn't have been when I was a teenager, if I was sharing stuff with people my own age).

I was comparing it to Twitter, Facebook and (original) Instagram, etc, in which a much greater proportion of users are posting content rather than just consuming.

It's the having time to think about what you're writing/posting that makes people more comfortable posting on those platforms. And of course you can hide behind an avatar on those platforms too.
