Since everyone seems to throwing their favorite format into the ring (), I will too: EDN [0] * no enclosing element (i.e., can be streamed) * maps, lists, even sets * tags (like "Person". UUIDs and timestamps are built-in tags) * floating point numbers * integers * comments * UTF-8 * true booleans * no need to worry about too many or too few commas in the right or wrong place Implementations in almost every language under the sun [1]. The format is simple enough that it's easy to implement, verify, and test. No strange string interpretation craziness (see YAML and "Norway problem"), no ambiguity between FP and integers (see JSON), comments. And if your editor has rainbow parenthesis support, reading is actually a pleasant experience.
