User analytics / metrics / karma / reputation system.

One possibility:

• per project: user's repo is the percentage of LoC additions to repository

  If ever comment upvotes Idea: A voting system for comments #209 get implemented, also give some weight to comments. This would hugely help closing issues.

• per user: take the above, multiply by the number of stars in the repo, sum over all repos.

  Show a per language rep.

More advanced: if a user has higher rep, his star has greater weight (a la Google Rank).

More advanced: if a user has higher Javascript rep, give higher weight to votes on Javascript repos.

Rationale: Stack Overflow works because of this. We all know that reputation is meaningless, yet many of us keep contributing because of it.

I'd love to hear new ideas and about existing API based user analytics systems.
