Sites like MN need its users to generate content. We are its product. All services need something unique about them to differentiate themselves from the competition. At one time what differentiated MN from its competitors was that there were more intelligent discussions on here.
Now the same type of discussions happen on MN as elsewhere.
What differentiates MN from its competitors are the large number of feminists on here. That is what is unique about this site. To keep going as a decent ongoing commercial concern, MN needs its feminists. Otherwise it has nothing to differentiate it from other sites.
N.B What differentiates NM is that its local sites are far superior to any other site.
