A JSON API is the methods & options that are available for (de)serializing your native Python or Django objects into useful JSON.

Perhaps there's a more narrow 'scope' defined for this project, but simply from the title, it seems an 'effective' Django developer would appreciate guidance for the best ways to do AJAXy things (including, especially, RESTy web services for backing AJAXy front-ends).
