I think it's quite hard because a majority of users here come to advertise or find offers, due to FWS being so big. So the user base is exponential, while if you just start out some people would think it's too much a hassle to advertise on a site with almost no traffic, and likewise people seeking hosting will not find a great variety of offers. FWS started off early to took control of a large portion of the free web hosting niche, when there were not many forums dedicated to free web hosting.
Basically it has a good start.
