I glad to see Git news on Phoronix.
Wait, they are having feature changes during the RC phase? Do they not have freezes?
I find revision management systems confusing and difficult to use.
Is there any crash course into Git?
Like Git for dummies?
Is there any good easy-to-use free open source software GUI for Git?
Pro Git is a good read for git newbies (I know as I am one of them), and then when you learn the basics it's just a matter of using Google for solving specific issues.
As for GUIs some IDEs include support for Git so it's just a matter of pressing a few buttons, although it's almost a requirement that you know how to properly use Git and are familiar with the jargon to begin with. Git itself includes the gitk command which opens a GUI interface, but there are other stand-alone alternatives like git-cola.
I tend to mainly use git-cola as well.
Github also has some nice totorials:

I also recommend the git-scm book linked above.
I like how people have found cool uses of Git beside as a source code revision management system.
There are Git-powered wikis that keep the wiki edit revisions using Git.
There are cloud file storage services, archival systems and backup solutions that use Git to keep file revisions.
There are Linux distributions (such as Funtoo) that use Git for their package management system and rolling distributions for binary bleeding-edge snapshot.
