I have decided to talk at BarCampIreland this Saturday in Cork.  I am going to talk about AJAX Asynchronous JavaScript and XML. The title of the presentation is

AJAX, How a 'toilet cleaner' is improving website interaction

I have decided to pitch my presentation at a non-technical audience as I suspect that a lot of the people attending would not need to know about the differecnce between synchronous and asynchronous coummunication but would like to know what you can achieve with it.
