I grew up with Linux and have used cvs, svn, git, and mercurial, not doing complex stuff, just basic. Out of all of them git is the most inconsistent and difficult to learn, both at the command level and in trying to deal with the docs and community around it. Everyone seems to think everyone else is a mathematician and every doc or message has this air of “if you don’t intrinsically understand DAGs then you’re just not worthy to use this tool”.
