a good post about JSON/XML debate
http://www.b-list.org/weblog/2006/12/21/i-cant-believe-its-not-xml

quoted from the above link:

1.The answer is that JSON works because most people don't really need all that overhead, and because it's often possible to do really interesting things with really simple formats.

2.But once you get past the egos and the attachments to this or that language or tool, the XML/s-expressions debate basically comes down to XML people saying, "OK, you've got s-expressions, and they're pretty cool and they solve your problems. But they don't solve my problems, so I need something else."
