Nothing of value has ever come from github.
There isn't a single software project worth using that has come from github.
Any important software project that appears on github is only a git mirror and doesn't accept pull requests or use the issue tracker.
All of github's site features exist only to enable non-developers to "interact" with software projects in unhelpful ways.
Some examples include
>ability to clone other people's repos without knowing how to use git
>ability to edit code in browser and push commits without knowing how to use git
>ability to create unsolicited and passive aggressive pull requests without knowing how to code
>emoji support, upvotes and social networking features let you feel important without writing a single line of code
It's not uncommon to see github accounts containing nothing but forks of other people's repos, lots of commit activity and zero real code written.
Why do people still treat github like the "de facto" code portfolio site?
Having a github link on your resume is the literal equivalent of having an @yahoo.com email address on your resume.
It's the mark of the self-taught "developer" that doesn't give a shit.
Keras?
nodejs :^)
Some projects on GitHub are top notch like mpv, rtorrent and golang.
The thing I hate the most is the social aspect. It looks like a children's playground while it should be dead serious.
