If you count private repos, my streak is getting rather ridiculous. 307 days so far: http://geoff.greer.fm/images/github_streak.png
I suggest you email <firstname.lastname@example.org> to let them know more than one person would like the feature :)
your graph looks similar to the authors. Huge sprawling areas of meaningless changes, punctuated by actual work, which more or less was consistent throughout history.
Do you feel this is a meaningful metric?
Also, I want to write software. If I didn't, doing it every day would take phenomenal willpower.
I am far more proud of commits that solve blocking issues for other people than I am of the plethora of minor changes and additions to personal projects.
However, after learning that many of the commits were to his personal website, my enthusiasm quickly faded.
Number of commits is a vanity metric.
