I don't think there's just been the one Ed for a while. Not quite sure how many there are at the moment but I think there's a Weekend Ed, and maybe still a Night Ed, not sure. But as far as I know the daylight-hours gnome is always the same person.
As for inconsistency, well, it's a bit like being among friends; you adapt your approach to what you see as their strengths or weaknesses; you laugh at some people you think can take it, not at others you perceive to be a bit lacking in self-esteem; those in trouble you try to help as best you can. As long as Eds and mods aren't meeting somewhere to ensure uniformity of approach, I think that's the best we can expect.
