I'm not happy that it's YAML but it's become ubiquitous. Sure, there are lots of other formats that others have mentioned, but I'm sorry most of them are positioned as "it's better than YAML!" and the fact that everyone is mentioning YAML, even if it's about the things it does wrong (and boy does it do things wrong) still means that YAML is on everyone's mind.
I think it's YAML.
