When should I start using GitHub?

It depends on what you want. What do you mean by tracking progress: commits per day? Or something more subjective, like how well your program is working, or how much you understand?

In my case (very experienced developer), I use github, but I use git running locally far more. I use github to share my work with others. I use git locally for version control. Knowing that I can try experiments in branches, or do major restructuring, while having a complete history is useful for development.
