I have fond memories of Hg/mercurial, and remember Bitbucket dropping support. Just seems strange in today's technolandscape to have anything as a single-sourced option. But clearly git did "win". Now wondering if that will generate a demand for those who don't like the monopoly to push something else. Guess the question is, what does a better version of "git" look like and does it have to be compatible to have a change to get off the ground?
