I'd like to see an algorithmic grading system that grades every repo publicly on things like: number of (transitive) dependencies, regularity of releases (explicitly not frequency since some things release reliably once a year), test coverage, and so on.
I'd like this to be public so that anyone can enter in a package and check out its score. My thought is that over time this might influence/produce a natural selection of only high quality repos.
My other idea, which is what this post is getting at, is that some group of devs band together to build a "distribution" of reliable JavaScript packages like every Linux distro does with the packages they distribute.
