I found a great site for developers to find out more info about AJAX, XML, JSON, .net, php, and pretty much anything else you can think of. Specifically I was looking for more information on JSON. This site describes JSON as being clearer and has less redundancy than xml does. It goes on to say that JSON is ideal for data interchange since each instance of a JSON document describes only one object with nested object, arrays, strings, numbers, boolean values or null values. The biggest plus I came across is that you can parse JSON with one line which saves time and looks neater.
