Kilimanjaro's JSON data-island example is certainly more readable. OTOH, with that approach there's the risk that, during maintenance, the data island will be overlooked and will become inconsistent with the human-readable information.

Edit: Perhaps that risk could be mitigated by having the human-readable markup issue a JS call to the data island, which would have the benefit of being DRY-compliant.
