Key Git Concepts Explained the Hard Way

While I mostly agree with you, I used linear VCS systems (mostly Perforce and SVN) for decades, and I still have no idea how they actually work. Git is fairly unique in that it basically forces you to understand how it works in order to use it, which I think is a major failing. I mean, it's nice that you can understand it and that that knowledge means that you can be more effective with it, but I don't think it should be compulsory. Currently it is compulsory for anything but the simplest workflows.

This doesn't seem specifically a linear vs distributed VCS thing, as much as it is a unique property of git. I previously used Mercurial, and at no point did I feel I had to understand how the VCS stores its commit graph in order to know what running some set of commands will do.

git is unique in its apparent assumption that it's nothing more than a series of convenience scripts that let you work on the raw filesysten representation a bit more easily. In a way it's more a filesystem-level representation of a DAG with some sugar on top, than it is a DVCS.

Ditto. I've used Darcs, Mercurial and Bazaar, all are distributed, all have various levels of issues, but none of them required that I understand everything from the storage model up in order to actually get a grasp on them. I still have better intuition for Mercurial than Git (and long for a number of its features like GIVE ME FUCKING REVSETS ALREADY) despite not having seriously used Mercurial in years and having no idea whatsoever what goes under the CLI (and not caring a whit).
