> less human-readable version of JSON

Please provide an example, how YAML can be less readable than JSON. I struggle to think of any.

Indentation based structure isn't really a good thing in my eyes, where the format of the document encodes semantic meaning. With JSON, you can display it how you want, and because it's bracketed it will still encode the same data.

Also I really don't like the hyphen notation... This is very unreadable to me:

  - a
  - b: c
  - - d
