Community moderators?

I think I read all of the documentation and at least skimmed most threads here and haven't found much on how moderation will be handled (I'm sorry if I missed a post where this is mentioned, it's very likely!).

Basically, will it be like on reddit, with users volunteering? Or will there be more of an "admin" caste handling that on a higher level? Also I know Deimos made AutoModerator so...

Just wondering since I've long thought that good moderation is all that really helps in keeping subreddits quality.
