I'm not familiar with Backbone but isn't `model.toJSON()` unnecessarily removing useful data types (like Date) that aren't available in JSON ?

You're probably thinking of `JSON.stringify()`. `model.toJSON()` just returns a clone of the models attributes object.

So `model.toJSON()` isn't supposed to return a JSON-compatible data structure ?

It's supposed to return an object that is suitable for turning into JSON, but it won't convert any of items members. JSON.stringify relies on the toJSON functions of the members to serialize themselves.
