I guess that's another way to go about it. I don't know how git deals with reindenting, refactoring etc, and you might lose context, but you could probably find it again.

It's kinda nice having it right there in the code though.

I use an iterative blame tool (magit-blame in Emacs) and it generally does pretty well for me.

I prefer having the author out of the way and looking it up when I'm curious. I can see how others might prefer the opposite.
