I do think it's important to factor the influence the charts had on the quality of user that would join the forums. Smeags said it best - weekly numbers gave VGC it's niche. That niche was particularly inviting of academic, analytical discussions about video games. You have to be a very specific type of game fan to be drawn to a website because of sales numbers, and that forces in the brand of community we have here.
I think that's what a lot of people are referring to when they comment on how good and intelligent the community is here. The charts were the seed that nurtured a community like that. Even if you're not informed when you join, I truly believe that the critical thinking demanded in such a forum and makes every user here just that little bit more intelligent purely from that exposure.
