Most site names here are worded as a general topic, not the people who practice it. For example, there's a site called "Aviation," not "Pilots." (I've found that the only exception to that rule is the "Android Enthusiasts" site.)
Plus, people will get the misconception that this is related to Stack Exchange moderation or that this is some kind of Stack Overflow-/Stack Exchange-moderators-only site where only 10kers or people who fall into that category get to talk.
Why can't it be named Moderation instead? The consensus in the related question is that the word itself will be kept, but it doesn't look like anyone's ever thought about changing how it should be said.
