I think GitHub is being more popular among &quot;non-developers&quot; because version control is beneficial for all sorts of projects.<p>My favorite example of a &quot;non-programming&quot; project is Hadley Wickham&#x27;s Advanced R book (<a href="http:&#x2F;&#x2F;adv-r.had.co.nz" rel="nofollow">http:&#x2F;&#x2F;adv-r.had.co.nz</a>) which is hosted on GitHub and powered by Jekyll, knitr, and pandoc. I hope more authors decide to publish this way.
