Who are the most prolific creators you know? Why do you follow them?

I just (soft) launched creatorlist.so, where I want to help collect the world's most prolific creators. There are currently 3 categories: 1. Startup 2. Marketing 3. Psychology What other categories would you ad? Who is actively creating on a big social media (Twitter, Instagram), their own website with a blog, a newsletter, podcast or even a YouTube channel? I would love to learn about them and add them to this list! (Any feedback is also appreciated!)
