"How Git Works" has been out for 4 months now and it's SO nice to read all of the reviews from people who are learning from it

@b0rk
A branch in git is a 41 byte file containing a commit id.

So yes, git -D does delete the branch. It does not delete the commit the branch refers to.

Other branches, tags and commits may refer to the same commit id, and checking that is the job of git gc.

@leeloo you don't really have to be this person. You can just not. Think about it.
