What exacty do GStaff and Nick Breckon do? They're very rarely on the forums, and Pete Hines seems to have taken over the whole "jetsetting around the world demoing for the press" gig. So again- what the hell do those guys do?
They are on the forums many times throughout the day. This forum covers quite a number of games. They are also posting stuff on Facebook and twitter throughout the day, they keep the Bethesda Blog up to date, they assist with things like presentations at E3, they keep the moderators in line, answer emails to Bethesda and themselves (including pms) and I assure you somewhere on their job description it says "and all other duties as assigned". That is a lot for any two people to keep up with.
In their spare time they try to squeeze in a bit of gaming for pleasure, wives, girlfriends, pets and on rare occasions they get to sleep.
