With the increasing popularity and availability of the Internet, differing opinions arise frequently. Though they are often expressed via flaming and other forms of argumentation, which consist primarily of assertions, there do exist formalized debating websites, typically in the form of online forums or bulletin boards. The debate style is interesting, as research and well thought out points and counterpoints are possible because of the obvious lack of time restraints (although practical time restraints usually are in effect, e.g., no more than 5 days between posts, etc.).Forums are Moderated and welcome online debaters in a friendly format so all may speak their pros and cons. Many people use this to strengthen their points, or drop their weaker opinions on things, many times for debate in formal debates (such as the ones listed above) or for fun arguments with friends. The ease-of-use and friendly environments make new debaters welcome to share their opinions in many communities.
There have been two World Online Debating Championships, run by Debatewise and IDEA.
