This could be good or very bad. The only way I see keeping from going bad. Would be allow peer-review of added content.
Not editorial peer-review. But user feedback peer-review.
Not open forum review, but by private comment. If the editor, sees value in the comment, action can be taken. If not a
rebuttal comment back as why the edited action should stand.
If multiple comments are received by the editor about a change. A further contemplation of the edit could take place.
Then no action by ADMIN would be needed.
If too many negative comments are given to an editor, editorial access should be revoked. I would want to keep the
wiki in high standards. The wiki is used by way to many learners to teach the wrong way of doing it.
There are many ways to say A=A+1, but not arrive there in a roundabout way. The wiki should reflect that.
