Why so much moderation?
It used to be only a handful of articles had moderated comments, now it seems like all of them do. I could understand if there were a lot of problems with spammers or the like, but if there have been I sure didn't see them in the pre-moderation days.
Waiting for comments to be moderated reduces the flow of conversation as you can't see all the latest posts when you comment so there's more duplication and less ability for back and forth. I can see the need in some cases, but maybe allow those who have been around long enough to earn badges be unmoderated? If they prove they need moderation pull their badge and make them earn their way back to your good graces.
