>XML is a better format than JSON.

That's quite absolutist - I can see why you see it as an unpopular idea. For me, the context where a tool is used is key.

XML is good if you have document-oriented data or want to use XML's namespacing.

I personally prefer JSON to XML in most other circumstances - which are most of them.

I happen to agree with you about YAML, but I don't think that's as controversal.
