Well, I will. It's much harder to understand than XML!

I produced a lot of XML in years past and none of it was ever broken -- well, wait, the very first time I programmed something to exchange data, I misunderstood one key name, but the structure was right, dammit.

JSON? Man, wrong, wrong, wrong so many times. Maybe it's me, maybe I just never grokked it fully, but I hated it and am happy to be retired and never have to deal with it again!
