The APDA Community has pooled a collection of cases as per Jake Campell's proposal on the community forums. These cases have been subdivided into categories for convenience.
Policy - This includes cases that require debating the merits of various possible government actions, but does not fall into any of the other categories.
Economics - Debates about microeconomics, macroeconomics, finance, and business are included in this category.
Philosophy - Debates about ethics, political philosophy, metaphysics, and other philosophical topics fall into this category.
Other - Not all cases fit neatly into one category or another. This is a miscellaneous category for those cases.
