I liked the concepts a lot. But the money part was ambiguous.
As in:
1. Get fascinated by some area a community is interested in
2. Dig into it, find and overcome challenges
3. Create an offshoot community around your insights
4. ???
5. Profit
I feel like Ken in the Barbie Movie had 1-3. He was really into "Beach". And lots of people liked "Beach". But that didn't lead to any money in the real world.
A follow up essay on that missing link would be great.
