MediaWiki should require users to view the differences made by the last editor of an article when submitting a new edit (ie, the last collection of contributions to an article by one user). Thus, everyone becomes a member of Recent Changes patrol, and much more vandalism will be caught. This could be as simple as sticking in the content that normally appears when you click "diff", above/below the editing box, so that the bright red text can easily be noticed. Then, there could be a checkbox (or maybe it's only available to admins) that says "revert last user's edits". So, you can rollback the previous edits while contributing your own. Very quick and simple, and will definitely cut down quite a bit on vandalism.
This would be very inconvenient if the last diff is enourmous.
A reasonable objection. I suppose the diff would ideally be after then submit button; so the user can see it before pushing the submit, but wouldn't be too much in the users face.
