NSG has more posts because of how broad it is. If a member is cruising NSG odds are far better that he will relate to a topic eneough to post on it then if he were in SG, becuase NSG has a shitload more topics. The ski gabber probably gets a lot of reads because thats where the info is, what a lot of people are here for, and they are more likely to click on a thread out of interest to read then interest to post, start an arguement, etc as in NSG.
