For reference, see the language description at http://json.org/.

I'm lazy and have trained myself to use single quotes to save the  
effort of hitting the shift key in javascript, but it does become  
important in other languages like PHP where double-quoted strings are  
different from single quoted strings.

I don't really have a preference for coding objects in javascript (a  
minor preference to no quoting of keys in objects), but if we are  
preparing a JSON string for consumption elsewhere then it should  
follow the spec and not rely on javascript's flexibility.

Cheers
