@krinkle @evan I'm actually not keen on the idea of looking at only repos referenced in package managers, as the set of repos that contain software that gets packaged is, I'm pretty sure, a pretty small subset of all public git repos - this feels a bit, in comparing to the social networks, a bit like only including "users who are verified" or something. Yes, this is a certain kind of useful, but it's likely to be skewed compared to the general population. My hypothesis is that these are going to be even more centralized on github, but we can test this! :)
I'm currently trying to extract this information from nixpkgs, which has about 140k packages in it, as a first test, we'll see how it goes!
