Seems like an unusually high ratio, 1:12.5
A lot of lurkers? Or maybe *ghasp* people only come to this site for sales and not the forums?! That can't be...
Now, how to get those 1,700 extra people to contribute to this site?
Edit: Just for comparison, heres Neogaf's numbers:
"Currently Active Users: 1987 (692 members and 1295 guests)" Nearly the same amount total, but only a 1:2 ratio.
