What is it that Fluther looks for when choosing new moderators?

I’m very curious. Over the past few years, I’ve paid close attention to the new mods when they appear and I can’t seem to find any one or two qualities they have in common, other than them not being overly snarky or controversial jellies. It doesn’t seem to be length of time on this site, as at least one mod appears to have been around less than a year.

Anyone care to enlighten me?
