Wikipedia editors are divided between those who are administrators, and so have greater access to online articles, and non-administrators who do not have such access. Clearly, the admins have more power than the non-admins.
By looking at the changes in linguistic style that occur when people make the transition from non-admin to admin roles, Kleinberg and co cleverly show that the pattern of linguistic co-ordination changes too. Admins become less likely to co-ordinate with others. At the same time, lower ranking individuals become more likely to co-ordinate with admins.
Wobei die Forscher anscheinend nur die englische Wikipedia erforscht haben. In der deutschen wird das natürlich komplett anders sein.
