Maybe some "junior" type of moderator could be established who can only approve posts but can't delete/nuke/ban/etc. And there could be many of those, like a dozen on a busy board. So that the flow of acceptable newbie posts wouldn't be impeded much, but any garbage would have to wait for "senior" moderator's decision.
It would be more effective this way,it shouldn't be a difficult task for the "junior" moderators to spot a fairly decent post.
This proposition isn't meant to simply restrict half decent posts but totally garbage/redundant and over discussed topic..
That way it'll be easy task for the "juniors" to approve a post,while the extreme garbage ones are moved over to the main moderators to decide what to do with them(ban/nuke/delete/etc)
In the BD section we could have about 10 "juniors",there's so much work to be done on that section..
The only issue now could be payments for the new moderators(That solely is theymos's call)
