That is if JSON content coming to a web client is properly formed. 
During the
development stage when a client fetches some JSON content read from the 
server's
filesystem (say metadata descriptor of a dynamic grid object) it is not 
guaranteed
to be properly formed.  This is when inspecting "raw" JSON at the 
client-side's
debugger comes in handy, and protocol succinctness brings value.

At least Javascript Object specification came well before JSON and 
deserves a merit.  Choosing JSON name for the protocol created a lot of 
confusion as many people think that it has much in common with 
Javascript Objects.  Alas, the issue with double-quoting object keys has 
been discussed on the web quite a number of times...
