How to measure a Emacs geek

Me, for example.

The first day I changed my .emacs.d:

master $ git log --pretty=format:'%C(yellow)%h%Creset %ad %s %Cred(%an)%Creset' --date=short|grep "`git config user.name`"|tail -n1
11fd85f 2011-08-31 eim (Chinese input method) (chen bin)

How many times I modified my emacs.d since then:

master $ git log --pretty=format:'%C(yellow)%h%Creset %ad %s %Cred(%an)%Creset' --date=short|grep "`git config user.name`"|wc -l

672
