Tool for peer-reviewed no-bump mass retagging
Most would agree that it is beneficial to add quality, relevant keywords to a post. It helps them be found appropriately (a sort of "optimization").
However, adding tags to a number of posts in one sitting is discouraged, because it floods the "active" area, hurting the visibility of new posts.
Wouldn't it be better for posts to not move up in active when only tags are added/edited?
I do think that when tags are added they should still gain more visibility within a given tag.
