It seems to be the only site out there that consistently delivers sales numbers in a very easy to read format for comparison's sake. But it seems to only be getting a few thousand members on at a time.. I dunno, I would think it would be more popular.
Or is it just me again being paranoid? (like the "i can't believe there's 500,000 people buying a console every week, coz that would be 10 woodstock concerts going to gamestop..")
