I feel that depends on the formatting. Non-pretty JSON isn't very readable either. ``` (dict :name apple :ip 192.168.1.1 :nested (dict :property value ) ) ``` Is almost JSON.

Rivest's proposal includes an "advanced transport" representation, a more human-readable version. Here's a sample: http://people.csail.mit.edu/rivest/sexp-sample-a

S-expressions aren't inherently more difficult to read than JSON, it's just a matter of getting used to it.
