Introducing HanSON: JSON for Humans (github.com)

Add trailing commas and I will use this for my open source projects. I can't tell you how many time I've deleted the last property in a JSON object (such as)

    {
      "foo": "bar",
      "baz': "biz"
    }

to

    {
      "foo": "bar",
    }

which is invalid JSON.
