To Ajax or NOT to Ajax

That is the question

Asynchronous JavaScript And XML, or its acronym, Ajax (Pronounced A-jax), is a Web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire Web page does not have to be reloaded each time the user makes a change. This is meant to increase the Web page’s interactivity, speed, and usability.

But just like its cousin javascript, it can be abused:

AJAX is certainly a hot topic at the moment which has led to a number of sites using AJAX where its not necessary or appropriate. This is similar to the situation we found ourselves in when Javascript, Images, Animated Gifs, Flash, *insert hot new thing here* and pretty much every other facet that makes up websites came into being. At the moment, this means that the sign of a good design isn’t how its used AJAX but more where its chosen not to use AJAX. We can cheat a little by following some simple rules when deciding whether to AJAXify a function or not.
