Debatepedia is a wiki encyclopedia of pro and con arguments and quotations in important public debates from around the world. Think of it as the Wikipedia of debates where you can search and find provocative and timely arguments on anything that affects us. The site is a collaborative resource which uses the same wiki technology that goes into sites like Wikipedia. Check out the Contents Guide to see all the debate categories covered by this online debating resource. http://www.debatepedia.org

Debatewise is designed so that you can contribute (and read) on both sides of an argument before arriving at an informed decision. Readers can also vote on the debates that are running. The best debaters gather karma points and a mention on the leaderboard. https://debatewise.org/

Debate.org has a slightly different format than the above sites. Debates are initiated by one site member challenging another to argue an issue. According to the site, “Each debate is made up of 1-5 rounds in which each member can post their arguments and rebut the arguments made by their opponent. Once both sides have posted their arguments, the members of the community vote for the winner.” https://www.debate.org/

ProCon.org is the country’s leading source for pro, con, and related research on controversial issues. The site uses professional researchers and rigorous editorial standards to explore more than 80 controversial issues from gun control and death penalty to illegal immigration and alternative energy. https://www.procon.org/

The debates that take place and are archived on The Economist: Debates use the Oxford style of debating applied to participants in an online forum. https://debates.economist.com/
