Debatepedia is a great new addition to the ecosystem of Wikipedia spin-offs. It is a collection of debate topics run curated by the International Debate Education Association for the benefit of student debaters. The topics are carefully broken down into subquestions, with pros and cons logically presented, with links to evidence and advocacy groups.
This seems like a great resource for people interested in learning more about an issue, either to help understand all of the viewpoints, or to brush up on their opponents’ likely counter-arguments.
I would love to see historical debating points. The topics on Debatepedia are all current controversies. What about issues which are well-resolved now but were controversial in the past? What would the Debatepedia of 1907 or 1807 or even 1507 look like? Should women be given the right to vote? Is slavery acceptable? Can witchcraft be detected and cured? I think it would be fascinating to see how reasonable people of those times argued these points.
