Not criticism, but a couple of observations.
Math.SE and StackOverflow are very successful because questions there are self-contained. You have a very specific problem and it's easy to solve it when you know the field.
Economics.SE has questions that, well, depend. For example, a question I liked, Is foreign-financed Basic Income Guarantee inflationary?, is difficult to answer since it requires details (does current balance remain constant, should we count the substitution effect in, etc.). Nothing new; economics is about models that give conditional answers.
Still, does it make sense (and if yes, then how) to incentivize questions with more details or answers that contain references to complex models?
