I don't remember "Supports Git" being one of the seven signs that Git Christ the Savior has Risen.

> Mercurial is great, but it's not git.

Yeah -- it's easier to use. I've even seen Git users suggest that newbies to the world of DVCSes coming from Subversion or CVS might want to try out Mercurial first because it's easier to pick up, then migrate to Git because that's what the people suggesting this path use.

> It's a hassle to have to learn two ways of doing everything.

That's as strong an argument against Git as it is against Mercurial. Despite this, I've learned to use both -- because "it's about the code". I just choose BitBucket/Mercurial for my own projects; otherwise, I use whatever DVCS is appropriate to the project based on what the project's core team uses.

> Being intimately familiar with git's required these days, especially for Linux and Android programmers. Mercurial's not.

Hah. There are lots of Linux- and Android-related projects on BitBucket and otherwise developed within a Mercurial framework, too -- and not everybody is developing primarily for Linux and Android, anyway. Did you notice, for instance, that the majority favorite language of GitHub hipsters (Python) is using Mercurial now? Your narrow world is not everyone else's narrow world.
