You know what has alluded me until now but I feel is very true. The one quality which is overlooked is that if we really need a moderator, we need one who does not want to be a moderator. A reluctant moderator if you will. This applies in many walks of life and it often just works. Someone that does not want the role, but does it anyway because they will be good at it. It really applies in management. The best managers' are the specialists in their own roles, who have years' of experience, enjoy what they do and are respected in their field. They have zero want or will to manage, but they do it because they are the only one's that are going to do it right. They step up with that knowledge.
The reason for doing so is not for the power trip. This caveat is one of the top way's they will not intervene for stupid stuff, will allow active discussion without bias, and have zero agenda. Someone that is desperate to moderate here is more likely to go too far (not always, but more likely). What will these clown moderators at dpreview do with their lives. Just look at how that mako2011 banned Maoby in this thread for posting about this site. Do people get any more sad, pathetic and childish than that? Sum's up years of what I've seen there. Good riddance Dpreview.com
