why JSON strings? - easy portability - remoting-friendly - leads to very compact API - JSON parsing/generating overhead is IMO minimal and probably more effecient than creating (and collecting) tons of small java objects on the heap
I doubt this. In fact I think the situation with the small Java objects is even worse in the face of a JSON based API: typically a (de)serialization layer will create an additional set of intermediate objects which have to be consumed/translated into the domain objects of the respective implementation.
