Sadly no, it was a terribly anecdotal claim with no official evidence to back it up. I guess the point behind my claim is what do you mean by "working with git"? To me it is about checking code in, diffing, etc... which most people I've ever worked with do from the terminal. Occasionally I'll see folks want a gui for diffs (not really surprising since it's kinda fugly from terminal), but do most of the "work" from term.
So I suppose I shall digress and admit I committed a total failure at an internet statement on a decently technical forum.
in the words of Homer....
doh!
