Could an internal rep, voting and badges encourage good programming practices?

Question

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.

Something like

• 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?
