queenlua asked: Sorry if I'm being dense/pendantic, but—what's the difference between asking "What version control system do you guys use?" and "Do you use git?" Since you claim asking the latter is superior...
It’s just a bit of my bias showing :-).
I think that “What version control system do you guys use?” is passive and perhaps too forgiving.
I enjoy using git, so it makes sense for me to ask about it directly. If the response is “No.”, or “What’s git?”, I know things are not headed in the right direction.
