Update: This is really just a fleshed out combination of Let me reward a good edit on my question/answer & Rep for good edits?
If you like this idea I suggest you vote for them.
Part of the core aspect of Stack Exchange is to provide the best answer to a question, and so the best answer gets selected by the asker (giving the answerer points) and up voting of good answers (giving the answerer points).
When I look at a question with an answer, where there is an issue, formatting or more info could be added I am struck with a interesting issue: Do I fix the answer by editing or do I submit my own answer?
Submitting my own answer would be better for me because I could possibly get the selected answer points and/or up vote and thus gain points. Howeer the edit is better for the community: one answer which is best is easier for people to grok than reading 10 similar answers.
To this end I propose that if you edit an answer points could be allocated for it.
To prevent gaming, I would suggest that the answerer acknowledge that was a good edit. If the answerer does he gets 1pt (for being a good citizen). Bad edits, signified by a rollbacks, could carry a negative score like a down vote. This would promote more interest in checking edits and also promote the good ones. From this point on the editor gains 1pt each time the answer is up voted and 5pts if it is selected.
I am stating point scores, but I am not suggesting that they should be that, this would be up to the SE people who understand this.
Example 1:
- Question is asked
- Answer is given
- Answer is upvoted
- [Answerer gains points from upvote]
- Editor edits answer
- Answerer acknowledges good edit
- [Answerer gains 1pt]
- Answer is upvoted (second upvote)
- [Answerer gains points from upvote]
- [Editor gains points from upvote]
- Answer is selected
- [Answerer gains points from selected answer]
- [Editor gains points from selected answer]
At the end of the day the editor gained 6pts, 1pt for the upvote and 5pt for the selection. He does not get a point for the first upvote since it was before he editted.
Example 2:
In this example only one editor at a time can get the points, not 100% about it as maybe all editors should get points. Also not sure if the answerer should get points again for acknowledging a second good edit.
- Question is asked
- Answer is given
- Answer is selected
- [Answerer gains points from selected]
- Editor 1 edits answer
- Answerer acknowledges good edit
- [Answerer gains 1pt]
- Answer is upvoted (second upvote)
- [Answerer gains points from upvote]
- [Editor 1 gains points from upvote]
- Editor 2 edits answer
- Answerer acknowledges good edit
- [Answerer gains 1pt]
- Answer is upvoted (third upvote)
- [Editor 2 gains points from upvote]
At the end the first editor got 1 pt and editor 2 also got 1pt.
In summary: Make edits a valuable action so that people are attracted to editing more and thus providing better (and likely fewer) answers to the system.
