I review and/or edit some answers and I see common mistakes.
Would it be possible to add to the Suggested Edits review answers that may contain common spelling errors?
For instance 'jqeury', 'usefull' and other words the OP often mistypes.
The SO system would auto-correct answers that present those common mistakes and editors would review those auto corrections.
Why review auto-corrections?
Sometimes, it can happen that the system raises a false positive. A human check is needed to detect those specific cases.
What are the advantages ?
As it's possible to create new tags, it would be possible to create new common mistakes.
A user that creates a common mistake often detected would be awarded with one or more badges (1000, 5000, 100000).
The quality of answers would raise as they get less and less errors.
