I think github is moving there...
Currently it has graph on individual's profile that tells what he has contributed. - Something like OpenBadges can be added to "top contributor to repo" etc.
One can compare fork and see age of the same. So say original contributor is no longer maintaining it, one can check fork. Visually.
- A good value addition could be showing it somehow on front page.
Issue voting - Yes, number of people watching could be good.
My addition would be - Explicit mention of license mention on landing page. like google-code - tags like google-code
