Abstract
A pragma-dialectical analysis departs from an idealized model of a well-organized, fully explicit argumentative discussion. Some argumentative activity types come closer to this ideal than others. It is useful and important to apply the ideal model to reconstruct relatively well-organized and explicit practices as is done for example in argumentation in legal proceedings. But it is great fun to explore what happens when you confront the seemingly anarchistic and chaotic practices of Internet political forum discussions with such a model, at least when you do this with the subtlety and intelligence of Marcin Lewinski. He reports his findings in a wellwritten, very interesting study.
