I too think it would be best to find someone who logs on later, so the site can have a healthy dosage of moderators throughout the three main times of the day.
My nomination:
MEK...He's been here forever and seems to be online quite often.
...In the 6 years I've been here, I don't think I can recall him ever having any issues with other members. He always stays neutral on the sensitive topics that have come up over the years, so that's moderator quality behavior right there...Maybe he'll gain some more respect while he's at it, too.
