What is meta? ×  I scoured meta and have not found any
discussion on this topic.  I thought about it when I very much
appreciated an edit someone made
http://askubuntu.com/revisions/146161/2 which greatly clarified
my original title http://askubuntu.com/posts/146161/revisions
And then realized I often would have upvoted edits in the past
as well, I don't see downvoting as being so useful though
because you can really just roll back or re-edit if it is that
bad. So, downvoting becomes a little convoluted.  But, I do
think, allowing an upvote/downvote next to each edit may:    1.
Encourage good edits    2. Encourage more incentive to make
edits    3. Discourage bad/careless edits  All in all, I feel it
may be useful. Not so much a feature request as wanting to
understand why it doesn't exist. Any thoughts ?  share|improve
this question I guess logically, upvote/downvotes would have to
only be an option for revision /2 or greater. And would work on
a lower points system 2 points for upvote -1 for downvote. –  T
