Creating both are merits, of course.
But creating Linux should not be a merit toward Git. Obviously the experience would make Git better. But why did a better UI lose to an inferior one?
I'd love to be wrong because now Mercurial is sort of dead and I have to use Git every day if I want to work with others. I'd love to have a better attitude about it. So far it just looks like another thing that one because X popular guy made it or Y big company made it.
