Conduct a Paid Willingness Survey

Following the "Contract Algorithm Scythe" series, I plan to create a "Prediction Algorithm Hammer" series, about 10 articles covering theoretical knowledge, mm algorithms, pricing strategies, numerical simulations, case studies, and more.
Some time ago, I was heavily educated by the market and community leaders: free stuff isn't valued; setting costs and thresholds can maximize influence.
But I don't need to make money from this (of course, a better 🤣 could be possible); mainly, I just want to maintain traffic and popularity, so I'm looking for good ways to do that.
I initially wanted to collaborate with a platform, release the content there first, then offer quizzes, and refund money if not completed—if completed, no refund. But that seems too difficult; paying for courses also feels unnecessary—I can just communicate with my agent; paid subscriptions also seem off (my Twitter is deliberately set to the maximum 239u) because there's no feedback mechanism.
Everyone, please give some suggestions.
