Just thinking out aloud - we programmers love all this voting/badges/rep stuff so could a scheme like this be introduced into a companies code review process to encourage better coding.
You (or others on your behalf) can post a review (could be snippet, single commit or series of) for a code review
Others can comment on it (would be similar to answers in SE)
Badges can be given/suggested (some would be good, some would be bad like "Comment Desert" or some such)
You can vote up/down on the code itself and the comments and badges (e.g. if someone suggested a badge and you did/didn't agree)
The aim of a scheme like this would be
Introduce a bit of fun to encourage the use of code reviews
Improve quality (in this scheme both code reviewee and reviewers are likely to learn)
Reduce the chance of code reviews sparking 'ego wars'
Give some metrics to help measure individual performance
Could this work? Thoughts?
