I've used https://djangopackages.org/ in the past to discover cool libraries, but decided I wanted to build something with a slicker design. I also wanted to find "surging" packages that are gaining a lot of stars relative to the total star count. https://django.wtf/trending/. The same can be done for package maintainers: https://django.wtf/profiles/trending/
I'm considering open sourcing the project once I clean it up.
