Last time I checked, 5 of the top 10 questions on StackOverflow were about Git...

still true! but that isn't a great metric necessarily, as #10 is "What is the “-->” operator in C/C++?" https://stackoverflow.com/questions/1642028/what-is-the-oper... which is just a novelty rather than a common question

Maybe because like 90% of devs use git; there's no language or framework that is used by so many.
