There was a good set of advices about configuring git (I've learned some from them and posted mine things as well), but now I can't find it anywhere in SE (except of on various numerous SE mirrors).
Why is it deleted? Was it that bad?
Such poll type questions are not allowed on Stack Overflow anymore (or for that matter, anywhere else on the network). While I fully understand and agree with all of the reasons given for disallowing such questions, I'm against deleting questions which have some value to programmers and this is one among them.
I feel that old questions like this one, which are directly related to programming or the use of a programming tool, should be closed as "Not constructive", locked and a shiny "Exists for historical reasons" banner slapped on it (come on, waffles has been working hard on implementing this, so let's use it!).
Let me state that I'm actually even fine with mass deletion if there is some standard and guideline in choosing them. Right now questions are being deleted on whim and others that are even more egregiously off-topic/not constructive are being left alone because of personal preferences and some because it still gives them a chuckle. These arbitrary exceptions are totally unfair in a community that supposedly sticks to guidelines and faqs. It is extremely hard for the community to delete these questions too, because some of them require nearly 300 votes to delete!
Here's my list of questions that belong on present day Stack Overflow's hall of shame, that for some reason or the other have not been deleted:
I think I've made my point clear. We simply should not accept that a question fair and square on a programming tool (even if "not constructive") is deleted when something about nerdy t-shirts is allowed to remain! You can find more here. Delete all of these with extreme prejudice or draw up guidelines and stick to them, no matter what your personal preference is. If you're that attached, favorite it and then delete. That way, you can go back to it whenever you want.
Poll, list, "look what I've got in my pocket, what have you got in yours" questions are off-topic on all the SE sites.
The question you refer to falls into the sub category of:
