We'll be looking into redoing presentation and also examining the raw stats for sections. VG did fall into a bad slump a while back however. I'm not involved enough in VG to really know how it was just before the move and after.
No, it was not subforumed due to activity or lack thereof (it's been better of late too imo with that!), but due to a restructure of sections to trim down on sheer size of forum sections and etc. There'll be further presentation changes as well based on user feedback (given in City Hall atm).
