TikTok has a creator fund that incentives and rewards their creators. It is much closer to YouTube than Twitter or Snapchat. And I’m pretty sure it’s DAUs are way greater than both of those as well.
I regretted the Twitter comparison as soon as I reread my comment. I was thinking in broader terms — apps where the bulk of users follow creators and not personal contacts tend to grow and sustain very differently. But it’s so obviously most similar to YouTube, from a user perspective, it’s an accelerated YouTube experience.
