This came up on chat, and well, there's a few issues to be raised.
Folk who're editing tags tend to get adviced to edit a few tags at a time, and it kinda worked - we've having more people editing tags (yay!) in many cases at a sensible rate (double yay!), but we still end up getting the front page flooded (boo!).
What would be a logical way to settle this? De-emphasise tag edits? Have a tag-busting weekend set by the mods every quarter or so to handle these things? Even more stringent self-control in terms of the number of edits done?
