The idea that Wikipedia is epistemologically conservative may be counter-intuitive for many. Is not Wikipedia completely open and free? Don’t we know that anybody may write and edit this encyclopedia and that the editing process itself is transparent? Isn’t Wikipedia a fantastic example of international collective intelligence and one of the big successes of crowd-sourcing? Of course! But the big lesson of Jankowski’s work is that all this is not enough. There are still some emancipatory efforts to be made.
