Edit: but it really is a niche use case. Count the number of developers working, the number of lines written, for projects that are not the special snowflake of the Linux kernel. Line of business apps. Consultoware. Fuggin' code bootcamp students selfishly using other people's open source projects for their grad advancement. All this code that nobody, maybe not even the people writing it, cares about. Git is the wrong tool for those jobs, but because Torvalds wrote it, it must be good.
