A short post I wrote over at the SoundSoftware site.
Spoiler: The answer I gave was not “Mercurial can be understood by human beings”.
Let me know if you spot any mistakes (or just want to flame, of course).
A colleague pointed out that a big problem I didn’t help with at all is how to understand the difference between git and github, which is what people are often really talking about when they talk about sharing code with git. Ironic that we all move to distributed version-control systems and then appoint a single company to run a central server for them.
