Good arguments but using DOM Api in JavaScript needs many more lines than JSON parsing and access. jQuery made HTML access bearable for a simple reason: DOM sucks :)

Average Joe Dev does not reach the impedance mismatch you mention correctly.

The DOM interface is roughly the same in almost every language. The JSON interface is almost always simpler. It's no mystery why JSON is more popular. XML never died because of JavaScript developers.
