If the site wants to easily expand then it needs to start tracking retail pc sales. The pc fans on the site are by far the smallest group and by tracking the sales it would attract more pc gamers to this site.
Instead of focusing on expanding into non-sales related areas, you should be looking to expand the sales tracking. Track more markets etc. If that requires more people to be part of the sales tracking back end then so be it.
Furthermore I'd suggest adding as many (useful) analytical tools as possible, any increase in the flexiability with the data would be welcome. I have no ideas what these tools would be, its just a though.
