Yeah, hardly anyone cared what Linux used (a few years earlier before Bitkeeper it was mostly just patches). But Rails was a very early Github user, and the big Rails usage upswing coincided with that and helped drive it. I was a Python and PHP dev at the time, and that other stuff mostly predated Github and was scattered across all kinds of places. Whereas Rails and Github both kicked off about the same time, and practically no Rails devs or libraries used anything else. It was that fast growth and hype combined with the network effects of Github that drove git usage rather than what Linux used. The Linux contribution workflow was also pretty alien to Github focused webdevs.
