I'm usally confronted at YAML when I setup gameservers of some indie games (I'm looking at you Empyrion) and I find it extremely painful to handle.
When you have sevral configuration files where you have to change/tweak data I always end up pulling my hairs why stuff isn't working because of an extra space lying anywhere in the file.
Please don't use YAML for anything that has to be edited by a human
INI, XML, JSON are all formats that are more forgivable regarding that (oh and always trim anything you parse. The more you do to help against accidental input, the less admins you'll have ;)
