## Experiments 3 3.1 Conditions Of Experiments

Before dealing with results and observations of experiments, we present context of these experiments. For the first experiment, we worked with the development team of betapolitique. Betapolitique is a web blog of politic news.  The duration of experiment was three months (February to may 2007) during French presidential elections. No help nor explications were provided to users. There was no objective nor a subject of debate defined.  Users of betapolitique are anonymous to each other and were not forced to participate.  They could read their arguments on the right of the article (figure 6) and use a treemap (developed by the society Pikko www.pikkosoftware.com) to see which article was the most annotated (figure 7).
