While browsing the Articles for deletion [1] page at Wikipedia (um, for research purposes...I don't do it daily), I stumbled upon Debatepedia [2]. Their mission:

Debatepedia has been developed as an interactive educational resource for people around the world, focusing particularly on the field of debate. It has a powerful mission to improve the the quality and depth of debates, reasoning, and deliberation in communities of all kinds. It also aims to reveal where powerful policy-makers, individuals, and interest groups stand on debates (position pages), and how legislation, ordinary people, and the world are affected by them, helping answer the question, "Why do we debate?". Within the debate community, Debatepedia aims to become a multidimensional resource for uncovering evidence, as well as a socially productive outlet for the extensive research done by debaters and their talented minds. In addition to these argument-building functions, Debatepedia is also a place for debate clubs and schools to identify themselves, their histories, and milestones, all in the interest of building and showcasing the international, multicultural, multilingual world of debating.
