Don't see why it's a problem to be honest?
Most users on this site are impartial, it's only here, on this section where we form groups- with group A disliking Group B. You hardly think the Ed is going to choose a moderator from any of us lot do you? Somehow I don't think he's that simple!!
As 4get says- if you abide by the rules of the site- and lets be honest, they aren't exactly hard to follow if we all act like rational adults, we should be ok.
I think the only people who have to worry are those who constantly break the rules for their jollies, and quite frankly the day they get 'moderated' from the site can't come soon enough.
Incidently- where ha the Ed stated that the moderators will be chosen from the site?
