One important metric we should be tracking and sharing is contributors to the language and ecosystem. This is really really hard to do. We can obviously go for the low hanging fruit via GitHub and look at who committed to a repo but that often time isn't enough.
A few possible metrics that would be cool to track:
On the question of what it means to be a contributor, this will hopefully be taken care of by our 2021 GSoD proposal. This whole discussion was inspired by the NumFocus project survey where I had to say how many "contributors" Julia had which was quite a difficult question to answer.
This could be a cool JuliaHub feature too I suppose @ViralBShah @aviks
I have the answers for the metrics questions, wait for JuliaCon 馃檪
So long as the contribution goes to a repo (julia or package), it can be automatically counted. Even our docs usually go into the repos.
Other contributions are books published, tutorials, videos and such - which have to be done manually by someone.
