I'd like to see that. throw in an editor that allows you to suggest changes, then two others have to approve it for it to be actioned. Follow this up with the post in question having a link at the bottom 'Possible Changes Pending' so that others can be notified and then power it up with a Karma connection

(Formula:(PostKarma/10/Editors changes) rounded up to one would give a single editor 5 points for a fifty point article, five editors with approximately equal changes one karma each... or 1 each for 4 and two for the fifth editor who contributed between 20% and 40% of the approved editor changes)
