My main goal with this would be to contribute and make it better 
I imagine the community also has a lot of desires / suggestions (looking at “Feature Requests”), and you all don’t have time to implement them all … but we can!
Just a thought.
You could contribute to https://github.com/docker/distribution or https://github.com/docker/docker-registry, and then build something around one of those.
right. wouldn’t make hub.docker.com any better though too bad
It would, actually. This is the basis of Docker Hub.
