The point of github is being an easy place that you can point to to tell people "I hack, look here for proof". You can still point to other places or things. It doesn't have to be on github.
If you don't hack and are just in it for the career/job, don't bother.
That's what I wanted to know. My issue with Github was that it felt like open source rather than "look what I built," so I wasn't sure if I was missing part of the culture or just seeing things wrong.
I'm definitely not in it for a job, I was more curious about the reputation factor, as in - do I need to give code away in order to taken seriously.
Sounds like it's not so much about giving away code as it is using it to supplement your portfolio.
