JSON is STUPID

Quite frankly I've never touched JSON, but when you have a perfectly good solution which takes away processing power from the user why would you make the user do all the processing?

I would only EVER use Javascript for and only for giving the user a nicer experience ie through visual effects or even to the point of ajax even though I dont agree with ajax for things like Facebook have you used their site on a shit computer?
Its just a joke, it kills your computer (in terms of speed) and from my experience of that anything that adds processing power towards the user without good cause to then its a little pointless.
