I recently created a Stack Overflow chat room to whip low-quality edit reviewers into shape.
It… worked. Most of them said they would be more careful about minor/invalid/vandalism edits and that they didn't know minor edits were bad: after my complaining, they improved.
That leads me to think that edit reviewers should be educated more.
Is that ^ supposed to mean anything? Come on, there should be a Help Center article at the very least. A screen that needs to be manually clicked through that explains reject reasons and informs reviewers about how the system works would be even better.
