There are problems where you would want to be able to organize civil disobedience and need to be resistant against attempts of the government to shut your website down.
If you want to organize 150 people to come late to school to push back the starting time of the school, it might be important to keep the identity of the people secret until the project is finished. In the case of founding a new academic journal on the other hand you likely want the identity of the people who already committed to the new journal to be public.
