The trouble with yaml is that it's too hard to keep track of how indented something is if its parent is off the screen. I have to keep a t-square on my desk and hang it from the top of my monitor whenever this comes up.
That, and the fact that it has enough bells and whistles to that there are yaml parser exploits out there.
