Github is a lot bigger than just helping developers now. Rendering CAD files, Visualizing CLU maps. Github isn't working just on improving the developer experience. They're working on improving the entire collaborative process. I love that now they're helping even government be collaborative.

Just because its not focused on code doesn't mean you can dismiss it as "some intern" project.

Here is a list of free programming books on GitHub: https://github.com/vhf/free-programming-books

I hope it will help you and other developers write better code.

Yeah, this is just marketing. Like when they got all excited that the Linux kernel was being hosted at Github. It was just a mirror that Torvalds set up. Github is/was being used as dumb storage.
