With a syntax that's ridiculously easy to write a parser and generator for (with the one exception of high unicode character escape sequences being encoded as two \uXXXX escapes after each other which form a surrogate pair rather than one \uXXXXXXXX escape, which is a bitch to deal with unless you use UTF-16 internally). It's certainly easier to write a mostly-correct JSON parser than an XML parser.
