Now if you have a specific question about some aspect of Git compared to Mercurial...
So, when trying to get your bearings in a new area or get an idea of what the issues are, asking experienced developers what they think you should know is bad behavior that can't be allowed. The risk is just too high that between the useful answers there might be some that you couldn't use. Better to have no answers than to have that.
StackOverflow should not be about using experienced people as advisors; it should be about using them as documentation.
Getting started in a new area is what tutorials are for, not a Q&A site. I generally don't like deletionism, but in this case I understand the decision.
Would that be the git tutorial or the mercurial tutorial that is a better source than experienced developers for advice on how the two end up differing in practice?
