Haskell learners often struggle with understanding fold functions. Create an interactive tutorial that visually explains foldl and foldr with examples. Monetize through a freemium model, offering basic content for free and advanced lessons for pay. Start with simple examples, then add complexity and quizzes. Risk: Limited audience size.
