I'm no more  a"fan" of git than i am of drupal. Its a tool that has good 
value if you know how to use it and can frustrate the hell out of you if 
you dont.

It just has one more layer of intelligence/workflow that allows it/you 
to ignore changes in your working copy that you don't want to pay 
attention right now. If you're like me and have a couple things going on 
at once and want to commit your work in atomic chunks you can find it 
useful. If not there are git shortcuts for commits to ignore the whole 
layer.

You find that its wrong or it doesnt work? These are two different things.

HEAD is a special dynamic variable that refers to the most recent commit 
in the index. It is there so you don't have to type in the whole commits 
crazy ass SHA name. In that way it works EXACTLY like a named version 
tag.  (fyi HEAD^ equals "next to last commit" so git "diff HEAD^ HEAD" 
shows you the diff between the last commit and the one before it).

You can see what this is by interrogating the HEAD file in .git manually 
for fun. HEAD isnt a branch name like master or |6.x-3.x. Though i can 
see the point of confusion if im understanding you correctly.
