Well generally the decision to pick a moderator is made by those in charge of the boards, namely Aristotle, Jeff, or myself.
We pick moderators when we see the need for there to be some. That is, as the need arises.
We tend to pick people we feel are competent, reliable, and trustworthy with the position. We tend to look for people who post alot, and/or have been with the site for a long time and know how it operates. This is how I was chosen, back in the day.
That's pretty much it, really.
